ABSTRACT:
A pipe coupling device (2) for joining the ends of two pipes is disclosed. The pipe coupling device (2) includes a sleeve (4) configured to receive an end of a pipe and having an annular first abutment surface (6); a compression member (12) having an annular second abutment surface (10); a sealing and gripping assembly (8) for sealing against and gripping the pipe; and threaded fasteners for drawing the compression member (12) and the sleeve (4) axially together so as to compress the sealing and gripping assembly (8) against the pipe. The sealing and gripping assembly (8) includes a sealing member (14) and a gripping device. The gripping device may include an annular carrier (16) having an annular recess for retaining a gripping member (18). The gripping surface of the gripping member (18) and the annular carrier (16) are adapted for relative axial movement wherein the gripping member (18) may be moved into tighter contact with the pipe.
