A pipe coupling for connecting a pipe to a flange associated with another pipe in a sealed manner. The pipe ( 10 ) is formed with circumferential groove ( 10 a). The coupling comprises a gasket ( 20 ), a mounting ring ( 18 ), and a mounting flange ( 22 ). The ring ( 18 ) is elastically expandable, e.g. by being split, and formed with projecting rib ( 18 a) adapted to fit into the groove ( 10 a) and hold the ring affixed to the pipe ( 10 ). The mounting flange ( 22 ) is tightened against both the ring ( 18 ) and a counter-flange ( 12 ), through matching cone-shaped surfaces ( 18 c, 22 a).
