Abstract: A connector for joining two tubular members together includes inner and out concentric rings that are joined together in a manner that permits the outer ring to turn relative to the inner ring. The inner side of the inner ring has two seats to engage the ends of the tubular members that are to be joined together. The outer side of the inner ring and the inner side of the outer ring have camming members that when engaged cause the outer ring to exert compressive forces on the inner ring that in turn causes the inner ring to firmly grip the tubular members. The inner ring preferably has a gasket-like material in each of the seats that firmly engages the ends of the tubular members. When the camming members are disengaged, the ends of the tubular members may be inserted into or removed from the connector so as to separate the parts from one another.
