Connector having enlargement restraining means

摘要

A connector includes a body and a clip for fitting on the body. The body has a hose connecting portion and a pipe receiving portion. The pipe receiving portion is adapted to receive a pipe therein and includes a clip fitting part. The clip fitting part has an engaging hole for engagement with an engaging claw formed on the clip. The engaging claw moves from a protruded position for preventing removal of the pipe to a withdrawn position for permitting removal of the pipe from the pipe receiving portion as the operator forces the clip to be enlarged. An enlargement restraining device is provided that is operable to restrain the enlargement of the clip within a predetermined range, so that the clip can reliably resiliently return to the protruded position when the clip is released after the pipe has been removed from the pipe receiving portion.
