Abstract:
1. A system for facilitating coupling pipes at their ends in substantially fluid-tight relationship comprising: (1) Clamping means for clamping around said pipe ends said clamping means including at least one screwhole for receiving at least one screw for fastening, by securing at least one nut thereon, said clamping means over gasket means and said pipe ends, said at least one screw being configured such that it is loosely disposed in said at least one screw hole of said clamping means prior to fastening of said clamping means around said pipe ends; (2) gasket means for interposition between said clamping means and said pipe ends; and (3) resilient retention means, resiliently engageable with said at least one screw, for loosely retaining said at least one screw in said at least one screw hole while said at least one screw is loosely disposed in said at least one screw hole prior to fastening said clamping means together by securing said at least one nut with said at least one screw, said resilient retention means being resiliently positionable from the side of the shank and from the front of the shank of said at least one screw into engagement with said at least one screw to loosely retain said at least one screw in said screw hole prior to fastening said clamping means together by securing said at least one nut with said at least one screw.
