ABSTRACT:
A coupling for attachment to the end portion of a pipe having a circumferential shoulder in such end portion includes a coupling body which receives the end portion of the pipe therein and a set of jaw members which, after the end portion of the pipe is received in the coupling body, move to a closed position to engage the shoulder so that the coupling is locked onto the end of the pipe and the pipe cannot be pulled from the coupling because the jaw members acting against the shoulder prevent such movement. The coupling can be provided with sets of jaw members at each end to couple together two pipes with end portion shoulders or have jaw members at one end and threads, flanges, or other types of connectors at the other end. Valves or other fittings may be incorporated into the coupling between the ends of pipes being coupled.
