Abstract: A pipe coupling comprising a body with a bore adapted to receive the pipe as a sliding fit and formed with a recess for an O-ring to encircle and seal against the pipe. A nut threaded on the body has an internal wedge surface, and a longitudinally split pipegripping collar encircles and grips the pipe and has an external wedge surface which is complementary to and cooperates with the wedge surface in the nut. The external wedge surface on the collar is relieved intermediate the ends of the collar, by a rectangular-section annular groove so as to decrease the area engaging the nut without decreasing the effective overall length of the wedge surface.
