ABSTRACT:
A connector used in connecting a resin tube and a metallic pipe of comparatively small diameter comprises a connector body and a plurality of elastic pawl members. The connector body is formed with a large-diameter chamber. The peripheral wall of the chamber has a plurality of lock holes distributed in the circumferential direction thereof. Each elastic pawl member is assembled such that its rear end portion is passed through a corresponding one of the lock holes, bent and secured in place, and its front end portion resiliently retains and secures an expanded portion of the pipe inserted in the chamber.
