ABSTRACT:
A connector (10) for tubular members (12, 14) is disclosed including first and second connector elements (16, 18) each having U-shaped cross sections and first and second jaw members (20, 22). A set screw (30) is threaded into the central portion (24) of the second connector element (18) intermediate the first and second jaw members (20, 22) and has an end abutting with the central portion (24) of the first connector element (16). A collar (32) encircles the first and second connector elements (16, 18) and the set screw (30) intermediate the jaw members (20, 22), with the first and second connector elements (16, 18) being biased apart by an O-ring (38) positioned between the connector elements (16, 18) and around the set screw (30). The jaw members (20, 22) can be inserted in longitudinal insertion directions into the tubular members (12, 14) and the set screw (30) threaded into the second connector element (18) to separate the jaw members (20, 22) sufficiently to grip the inside surfaces of the tubular members (12, 14) with sufficient force to prevent relative movement between the jaws members (20, 22) and the tubular members (12, 14).
