    • A pipe coupling includes a body member (10) formed with a bore (11) for receiving one end of a pipe (P) to be coupled; a sealing ring (20) and a compression sleeve (30) receivable within the bore (11); a radially-deformable gripping ring (40) having one end abuttable against the compression sleeve (30), a securing nut (50) threaded on the body member (10) and engageable with the gripping ring (40) to move the gripping ring (40) axially and to effect a sealing action via the compression sleeve (30) and the sealing ring (20), and also to compress the gripping ring (40) radially to effect a gripping action of the pipe (P) received in the bore (11); and an axially-extending limit element (45) between the gripping ring (40) and the body member (10) effective to cause the nut (50), when tightened; (a) in an initial stage, to move the gripping ring (40) and the compression sleeve (30) until the limit element engages (45) prevents further axial movement of the gripping ring (40); and (b) in a final stage, to radially deform the gripping ring (40) to produce the gripping action, and then to compress the sealing ring (20) against the internal annular shoulder (14) of the body member to produce the sealing action.
