ABSTRACT:
A connector includes a body having a pipe receiving portion and includes a clip which cooperates with a removal prevention protrusion formed on the pipe for preventing the pipe from removal from the body. The pipe receiving portion has an inner diameter to permit insertion of at least the pipe. A clip fitting portion is formed on the pipe receiving portion and has engaging holes. The clip is made of resilient material and has a ring-shaped configuration. The clip has both circumferential ends confronting each other. The clip is biased in a direction to reduce its diameter and can expand its diameter for fitting on the clip fitting portion. Engaging claws are formed on the clip and adapted to be inserted into the engaging holes so as to engage the pipe. Each of the engaging claws includes a rear surface which abuts on the pipe when the pipe is inserted and which is formed as an inclined surface for permitting insertion of the pipe. Each of the engaging claws has one lateral surface in the circumferential direction of the clip. The lateral surface is formed as an inclined surface, so that each engaging claw is removed from the corresponding engaging holes when the clip is rotated.
