A clip apparatus or method for sheet materials comprising a clip member and a collar member. The clip member is resilient and defines a hinge portion, first and second finger portions extending from the hinge portion, and a ratchet portion formed on at least one of the first and second finger portions. The collar member is resilient and defines a latch portion, a lever portion, a latch opening, and a housing interior. The collar member acts on the clip member to place the clip member in the closed configuration. The latch portion engages the ratchet portion through the latch opening to inhibit movement of the collar member. When the collar member is in a disengaged configuration, the collar member may move relative to the clip member.

What is claimed is: 1. A clip for sheet materials comprising: a clip member defining a hinge portion, first and second finger portions extending from the hinge portion, and a ratchet portion formed on at least one of the first and second finger portions, where the clip member is made of resilient material such that the clip member may be deformed from a normally open configuration into a closed position, and the first and second finger portions do not engage each other when the clip member is in the open configuration and the first and second finger portions engage each other when the clip member is in the closed position; and a collar member defining a latch portion, a lever portion, a latch opening, and a housing interior, where the collar member is made of resilient material such that applying a force to the lever portion causes the collar member to deform from a normally engaged configuration to a disengaged configuration, and the latch portion extends into the housing interior through the latch opening when the collar member is in the engaged configuration and is withdrawn from the housing interior through the latch opening when the collar member is in the disengaged configuration; whereby the clip member extends through the housing interior such that when the collar member is in a first position relative to the clip member, the clip member is in the open configuration; when the collar member is in a second position relative to the clip member, the collar member acts on the clip member to place the clip member in the closed configuration; and when the collar member is in the engaged configuration, the latch portion engages the ratchet portion to allow movement of the collar member towards the second position and inhibit movement of the collar member towards the first position, and when the collar member is in the disengaged configuration, the collar member may move between the first and second positions; and the first and second finger portions define first and second gripping portions, respectively; at least one of the first and second gripping portions defines a line notch adapted to receive an edge line of the sheet material; and at least one of the first and second gripping portions defines a line tooth; whereby the line tooth defines at least a portion of a line projection adapted to engage the edge line of the sheet material; the first and second gripping portions define first and second line notches, respectively; the first and second gripping portions define first and second line teeth, respectively; and the first and second line teeth define a line projection adapted to engage the edge line of the sheet material. 2. A clip assembly for sheet materials comprising: a clip member defining a hinge portion, first and second finger portions extending from the hinge portion, first and second cam surfaces formed on the first and second finger portions, respectively, and a ratchet portion formed on at least one of the first and second finger portions; a collar member defining a housing portion, a latch portion, a latch opening, and a housing interior, where the latch portion defines a latch lever and an engaging portion that is normally disposed within the housing interior; whereby the clip member is displaced in a first direction relative to the collar member until the housing portion of the collar member engages the first and second cam surfaces; further displacement of the clip member in the first direction relative to the collar member causes the housing portion to engage the first and second cam surfaces such that the first and second finger portions are forced together; the engaging portion of the latch portion normally engages the ratchet portion to prevent movement of the clip member in a second direction relative to the collar member, where the second direction is opposite the first direction; and displacement of the latch lever relative to the housing portion causes the engaging portion of the latch portion to disengage from the ratchet portion to allow movement of the clip member in the second direction relative to the collar member. 3. A clip assembly as recited in claim 2, in which the collar member further comprises a belt portion, where the belt portion of the collar member engages one of the first and second cam surfaces. 4. A clip assembly as recited in claim 2, in which the engaging portion is formed on a latch projection, where the latch projection and the latch lever extend from the housing. 5. A clip assembly as recited in claim 3, in which the engaging portion is formed on a latch projection, where the latch projection and the latch lever extend from belt portion of the housing. 6. A clip assembly as recited in claim 2, in which: the first and second finger portions define first and second gripping portions, respectively; and at least one of the first and second gripping portions is configured to grip sheet material. 7. A clip assembly as recited in claim 2, in which: the first and second finger portions define first and second gripping portions, respectively; the first and second gripping portions define first and second sets of gripping teeth; whereby when the clip member is in the closed configuration, the teeth points of the teeth in the first set engage interlock with the teeth in the second set. 8. A clip assembly as recited in claim 2, further comprising a stop projection arranged to inhibit movement of the clip member relative to the collar member. 9. A clip assembly as recited in claim 8, in which the collar member is deformed to allow movement of the clip member in either direction relative to the collar member. 10. A method of attaching a structure to a sheet material, comprising the steps of: providing a clip member defining a hinge portion, first and second finger portions extending from the hinge portion, first and second cam surfaces formed on the first and second finger portions, respectively, and a ratchet portion formed on at least one of the first and second finger portions; providing a collar member defining a housing portion, a latch portion, a latch opening, and a housing interior, where the latch portion defines a latch lever and an engaging portion that is normally disposed within the housing interior; displacing the clip member in a first direction relative to the collar member until the housing portion of the collar member engages the first and second cam surfaces; further displacing the clip member in the first direction relative to the collar member such that the housing portion engages the first and second cam surfaces such that the first and second finger portions are forced together to grip the sheet material, and the engaging portion of the latch portion engages the ratchet portion to prevent movement of the clip member in a second direction relative to the collar member, where the second direction is opposite the first direction; and displacing the latch lever relative to the housing portion to cause the engaging portion of the latch portion to disengage from the ratchet portion to allow movement of the clip member in the second direction relative to the collar member. 11. A method as recited in claim 10, further comprising the steps of: forming a belt portion of the collar member; and engaging the belt portion of the collar member with one of the first and second cam surfaces. 12. A method as recited in claim 10, further comprising the step of forming the engaging portion on a latch projection, where the latch projection and the latch lever extend from the housing. 13. A clip assembly as recited in claim 11, further comprising the step of forming the engaging portion on a latch projection, where the latch projection and the latch lever extend from the belt portion of the housing. 14. A method as recited in claim 10, further comprising the steps of: forming first and second gripping portions on the first and second finger portions; and configuring at least one of the first and second gripping portions to grip the sheet material. 15. A method as recited in claim 10, further comprising the steps of forming first and second sets of gripping on the first and second finger portions, respectively, such that, when the clip member is in the closed configuration, the teeth points of the teeth in the first set engage interlock with the teeth in the second set. 16. A method as recited in claim 10, further comprising the step of arranging a stop projection to inhibit movement of the clip member relative to the collar member. 17. A method as recited in claim 16, further comprising the step of deforming the collar member to allow movement of the clip member in either direction relative to the collar member.
