CA 2142272

A coupling for attachment to the end portion of a pipe (60) having circumferentially directed shoulder (3a) in such end portion includes a coupling body (61) which receives the end portion of the pipe (60) therein and a set of jaw members (65) which, after the end portion of the pipe is received in the coupling body, moved to a closer position to engage the shoulder (3a) so that the coupling is locked onto the end of the pipe (60) and the pipe cannot be pulled from the coupling because the jaw members (65) acting against the shoulder (3a) prevent such movement. The coupling can be provided with sets of jaw members (24E-27E) at each end to couple two pipes (1, 2) with end portion shoulders (3a, 4a) or have jaw members at one end and threads (64), flanges (81, 83), or other types of connectors at the other end. Valves (figure 5) or other fittings may be incorporated into the coupling between the ends of the pipes being coupled.
