Abstract

A small-diameter pipe connector comprises a connector body and a socket body. The connector body has a channel, a stepped small-diameter chamber, and a stepped large-diameter chamber formed axially thereinside, whose rear peripheral wall portion defines a support wall. The socket body has obliquely-projecting pawl walls which are adapted to fit into axially-elongate holes formed in the peripheral wall around the large-diameter chamber of the connector body. In the assembled state, an expanded annular wall portion of a pipe is resiliently locked by the distal ends of the pawl walls in the large-diameter chamber, with the rear end inner peripheral surface of the socket body being supported by the outer peripheral surface of the support wall of the connector body.
