ABSTRACT:
A clutch is disclosed consisting of two parts, the first part being a tubular shell closed at one end, the shell having therein a resilient female clutch member that is held in position by lips on the open end of the shell. A male member is provided which is adapted to be received within the resilient member. The resilient member within the shell is cylindrical of a longitudinal dimension less than the space within the shell and of an outside diameter less than the inside diameter of the shell. The male member is made of a size so that the sum of its diameter plus the wall thickness of the resilient clutch member is greater than the inside diameter of the tubular shell, so as to create an airtight joint when the male member is inserted within the resilient member, but yet permitting air to escape around the outside of the resilient member and retarded only when disengagement is attempted, at which time the resilient clutch member will seal against the lip of the tubular shell.
