ABSTRACT:
There is disclosed a compact connector for stably connecting a metallic or resinous pipe or tube having a relatively small diameter less than about 20 mm, the pipe having an outwardly swelling annular wall. The connector comprises a connector body, seal members, a bush member, and a socket body fabricated independent of the connector body. The connector body has a small chamber in which the seal members and the bush member are inserted. The socket body has an annular cylindrical wall, arms extending circumferentially, and a pair of rectangular claw walls. The claw walls have tapering surfaces provided with openings at their rear ends. When the socket body is inserted in the connector body, the front surfaces of the claw walls are brought into resilient contact with the swelling annular wall of the pipe. The rear surfaces of the claw walls engage the rear end surface of the connector body.
