ABSTRACT:
An adaptor is provided with a threaded end for union with a garden hose, or the like, and a conically enlarged opposite end configured to fit about a wide variety of spigots and pipe ends. A worm gear clamp tightened about the adaptor squeezes annular ribs on the interior of the conical end into sealed engagement around a faucet spout or pipe. The conical end of the adaptor includes exterior annular ridges which position and retain an adjustable band of the clamp in alignment with an interior annular rib so that the action of the clamp is focused thereupon for an improved seal. The adaptor includes an internal reinforcement web or mesh to prevent water pressure-induced swelling of the adaptor.
