A pipe clamp for connecting two pipe ends together. The pipe clamp includes a clamp component in the form of an open band of metal extending from a first flange to a second flange. A sleeve is located within the band, and the pipe clamp includes a tightening mechanism for drawing the two flanges together to tighten the clamp. The clamp and sleeve components each have first and second openings that are aligned with the openings in the other component. These openings are sized to receive a button located on the outer surface of each of the pipe ends to thereby allow the clamp to be loosely attached to the pipe ends prior to tightening of the clamp.

What is claimed is: 1. A pipe clamp for securing first and second pipe ends together using a button protruding from a side surface of at least the first pipe, said pipe clamp comprising: a clamp component formed as an open band extending circumferentially from a first end to a second end, said band having a first opening located on a side surface of said band; a sleeve component positioned within said band and having a first opening that is aligned with said first opening of said band; and a tightening mechanism that includes at least one fastener connected to said ends of said clamp component to draw said ends together for tightening of said clamp component; wherein said first openings are sized to receive the button such that disengagement of said pipe clamp from the first pipe end is restricted due to engagement of the button with at least one of said components at its first opening. 2. A pipe clamp as defined in claim 1, wherein said sleeve and clamp components each includes a second opening, and wherein said second openings are aligned with and overlap each other such that they are capable of receiving a second button that protrudes from a side surface of the second pipe end. 3. A pipe clamp as defined in claim 2, wherein said first and second openings are located at different angular positions on said pipe clamp. 4. A pipe clamp as defined in claim 2, wherein said first and second openings are located at angular positions that are angularly spaced from a slot feature of said sleeve component. 5. A pipe clamp as defined in claim 2, wherein at least one of said first and second openings is in the shape of an oval. 6. A pipe clamp as defined in claim 2, wherein at least one of said first and second pairs of aligned openings are shaped to receive a generally cylindrical button. 7. A pipe clamp as defined in claim 1, wherein said first openings each have one or more dimensions measured across the opening, and wherein the dimensions are each within the range of 5-20 mm. 8. A pipe clamp as defined in claim 1, wherein said pipe clamp is adapted to secure the first and second pipe ends together in a butt joint. 9. A pipe clamp as defined in claim 1, wherein said pipe clamp is adapted to secure the first and second pipe ends together in a lap joint. 10. A pipe clamp as defined in claim 1, wherein said openings have an axial width and a circumferential length, and wherein said circumferential length is greater than said axial width. 11. A pipe clamp for securing first and second pipe ends together, comprising: a clamp component formed as an open cylindrical band extending axially from a first axial end to a second axial end, and extending circumferentially from a first flange to a second flange, said band having a first opening in said band located adjacent said first axial end and a second opening in said band located adjacent said second axial end, said first and second openings being circumscribed by material of said band; a sleeve component positioned within said band and having first and second openings that are aligned with and underlie said first and second openings of said band, respectively; and a tightening mechanism that includes at least one fastener connected to said flanges of said clamp component to draw said flanges together for tightening of said clamp component. 12. A pipe clamp as defined in claim 11, wherein said openings have an axial width and a circumferential length, and wherein said circumferential length is greater than said axial width. 13. A pipe clamp as defined in claim 11, wherein said openings in said sleeve component extend inwardly from opposing axial ends of said sleeve component. 14. A pipe clamp and pipe assembly, comprising: at least one pipe having a free pipe end that includes an outer side surface and a button protruding from said side surface; and a pipe clamp, comprising: a clamp component formed as an open band extending circumferentially from a first end to a second end, said band having a first opening located on a side surface of said band; and a tightening mechanism that includes at least one fastener connected to said ends of said clamp component to draw said ends together for tightening of said clamp component; wherein said pipe clamp is positioned over said pipe end with said button being located within said first opening of said clamp component such that disengagement of said pipe clamp from said pipe end is restricted by engagement of said button with said clamp component. 15. A pipe clamp and pipe assembly as defined in claim 14, further comprising a sleeve component positioned within said band and having a first opening that is aligned with said first opening of said band. 16. A pipe clamp and pipe assembly as defined in claim 15, wherein said pipe clamp comprises a pipe coupler that can be used to connect said pipe end to another pipe end in an abutting, end-to-end configuration. 17. A pipe clamp and pipe assembly as defined in claim 14, wherein said first opening of said clamp components are aligned such that the protruding axial length of the first button extends outwardly through both of said aligned first openings. 18. A pipe clamp and pipe assembly as defined in claim 14, wherein the openings each have one or more dimensions measured across the opening, and wherein the dimensions are each within the range of 5-20 mm. 19. A pipe clamp as defined in claim 2, wherein said first and second aligned openings in said sleeve and clamp components are located adjacent respective first and second axial ends of the pipe clamp and are the only aligned openings in said sleeve and clamp components that are located adjacent said axial ends. 20. A pipe clamp as defined in claim 11, wherein said first and second aligned openings in said sleeve and clamp components are located adjacent said first and second axial ends, respectively, and are the only aligned openings in said sleeve and clamp components that are located adjacent said axial ends. 21. A pipe clamp as defined in claim 20, wherein said openings in said sleeve component extend inwardly from opposing axial ends of said sleeve component. 22. A pipe clamp as defined in claim 20, wherein said openings in said sleeve component are circumscribed by material of said sleeve component. 23. A pipe clamp as defined in claim 1, wherein said first opening in said sleeve component extends inwardly from an axial end of said sleeve component, and wherein said first opening of said clamp component is circumscribed by material of said clamp component such that, when the button is received in said first openings, said clamp is restricted from disengagement with the first pipe end by engagement of the button with said material of said clamp component.
