Patent abstract
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 (10a). 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 (18a) adapted to fit into the groove (10a) 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 (18c, 22a).
