A faucet has a spout and a pullout spray head connected to a flexible water supply tube and releasably connectable to the spout. The spout has a docking collar mounted thereon for receiving a connecting shaft of the spray head. The docking collar has an annular wall with a plurality of U-shaped slots which define a plurality of cantilevered snap fingers. Each snap finger includes a projection that fits into a groove in the connecting shaft when the spray head is docked. An elastomeric O-ring surrounds the annular wall at a point where the O-ring engages the snap fingers to bias them toward the groove. Ridges on the exterior surface of the wall retain the O-ring in place. The spout and docked spray head have parallel shoulders that define a mating plane. The projections and groove define a retaining plane. The mating plane is not parallel to the retaining plane such that rotation of the spray head about an axis normal to the mating plane will cause the projections to release from the groove.

1. A faucet of the type supplied with water by an extensible water supply conduit, comprising:a spout having a first shoulder which defines a mating plane; a pullout spray head connectable to the extensible water supply conduit and having a second shoulder, the pullout spray head being movable between a docked position in which the spray head is connected to and supported by the spout and a released position in which the spray head is separated from the spout, the first and second shoulders being parallel to one another when the spray head is in its docket position; one of the spout and spray head having a male portion and the other having a female portion, said male and female portions being engagable with one another in telescoping relation; retention members on the one of the male and female portions attached to the spout, the retention members defining a retaining plane and being releasably engagable with the pullout spray head such that the retention members disengage from each other when the spray head is disconnected from the spout, the mating plane and retaining plane being non-parallel to one another. 2. A faucet of the type supplied with water by an extensible water supply conduit, comprising:a spout terminating at a first annular shoulder which defines a mating plane; a docking collar connected to the spout; a pullout spray head connectable to the extensible water supply conduit and having a second shoulder and a connecting shaft which is releasably engagable with the docking collar, the pullout spray head being movable between a docked position in which the spray head is connected to and supported by the spout and a released position in which the spray head is separated from the spout, the first and second shoulders being parallel to one another when the spray head is in its docked position; and a plurality of snap fingers on the docking collar and a groove formed around the connecting shaft, the snap fingers and groove being releasably engagable with one another to releasably connect the pullout spray head to the spout such that the snaps fingers and the groove disengage from each other when the spray head is disconnected from the spout, the snap fingers defining a retaining plane, the mating plane and retaining plane being non-parallel to one another. 3. The faucet of claim 2 wherein the docking collar has a body including a base rim engagable with the first annular shoulder and a lower annular wall extending from the base rim at an angle thereto.4. The faucet of claim 3 wherein the docking collar further comprises a frusto-conical wall adjoining the lower annular wall.5. The faucet of claim 4 wherein the docking collar further comprises an upper wall adjoining the frusto-conical wall, extending at an angle to the frusto-conical wall and terminating at an inner rim.6. The faucet of claim 5 wherein the inner rim is parallel to the base rim.7. The faucet of claim 4 wherein the frusto-conical wall has a plurality of U-shaped slots extending there through to define the snap fingers.8. The faucet of claim 7 further comprising an O-ring surrounding the frusto-conical wall and engaging the snap fingers.9. The faucet of claim 8 further comprising at least one pair of spaced ridges on the frusto-conical wall, the ridges defining a channel in which the O-ring is disposed.10. The faucet of claim 3 wherein the lower annular wall has a U-shaped cutout to define a retainer finger which is engagable with the spout.11. The faucet of claim 3 wherein the docking collar further comprises a centering flange surrounding the lower annular wall.12. The faucet of claim 2 wherein each of the snap fingers has a projection thereon which releasably fits into the groove when the spray head is in the docked position.13. A faucet of the type supplied with water by an extensible water supply conduit, comprising;a spout terminating at a first annular shoulder which defines a mating plane; a docking collar connected to the spout, the docking collar comprising a body including a base rim engagable with the first annular shoulder and a lower annular wall extending from the base rim at an angle thereto; a frusto-conical wall adjoining the lower annular wall; and an upper wall adjoining the frusto-conical wall, extending at an angle to the frusto-conical wall and terminating at an inner rim, a pullout spray head connectable to the extensible water supply conduit and having a second shoulder and a connecting shaft which is releasably engagable with the docking collar, the pullout spray head being movable between a docked position in which the spray head is connected to and supported by the spout and a released position in which the spray head is separated from the spout, the first and second shoulders being parallel to one another when the spray head is in its docked position; and a plurality of snap fingers on the docking collar and a groove formed around the connecting shaft, the snap finger and groove being releasably engagable with one another to releasably connect the pullout spray head to the spout, the snap fingers a retaining plane, the mating plane and retaining plane being non-parallel to one another. 14. The faucet of claim 13 wherein the inner rim is parallel to the base rim.15. A faucet of the type supplied with water by an extensible water supply conduit, comprising;a spout terminating at a first annular shoulder which defines a mating plane; a docking collar connected to the spout, the docking collar comprising a body including a base rim engagable with the first annular shoulder and a lower annular wall extending from the base rim at an angle thereto; and a frusto-conical wall adjoining the lower annular wall; a pullout spray head connectable to the extensible water supply conduit and having a second shoulder and a connecting shaft which is releasably engagable with the docking collar, the pullout spray head being movable between a docked position in which the spray head is connected to and supported by the spout and a released position in which the spray head is separated from the spout, the first and second shoulders being parallel to one another when the spray head is in its docked position; and a plurality of snap fingers on the docking collar and a groove formed around the connecting shaft, the snap fingers and groove being releasably engagable with one another to releasably connect the pullout spray head to the spout, the snap fingers defining a retaining plane, the mating plane and retaining plane being non-parallel to one another, wherein the frusto-conical wall has a plurality of U-shaped slots extending there through to define the snap fingers. 16.
