ABSTRACT:
A coupling to connect pipe, including lengths of pipe, valves, hoses, and pipe and hose fittings, includes a body having an opening to closely receive the end portion of the pipe to be coupled. One embodiment of the coupling includes an end having a grooved end portion extending partially around the receiving opening with an internal groove therein and a recessed end portion extending partially around the opening and interrupting the internal groove, the end face of the coupling body being stepped and defined by both the grooved end portion and the recessed end portion. Jaw members move between a position to allow the pipe to move into or out of the coupling body and a position securing the pipe in the coupling body. An insert may be provided to lock the jaw members in position.
