ABSTRACT:
There is disclosed a compact connector for stably connecting a metallic or resinous pipe or tube having a relatively small diameter of about less than 20 mm, the pipe having an outwardly swelling annular wall. The connector comprises a connector body, seal members, and a socket body fabricated independent of the connector body. The connector body has a small chamber in which the seal members are fitted. The socket body has a pair of protruding resilient claw walls, an annular wall pushing the seal members, and arms extending radially outwardly and rearwardly. When the pipe is connected, the front surfaces of 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.
