Abstract

A joint for coupling small-diameter pipes comprises a body. The body includes a cylindrical joint wall defining a bore and a continuous cylindrical wall defining a stepped enlarged chamber in communication with the bore. The cylindrical wall includes a plurality of rearwardly extending holder walls having pawls. The enlarged chamber is configured to receive a seal and a bushing. A support includes a central hole, and a plurality of holes in surrounding relation to the central hole. When a pipe extends through the central hole, the peripheral wall of the central hole is engaged with an annular projection wall formed adjacent one end of the pipe, and the pawls are engaged with the holes of the support. The support may be in the form of a disk or in the form of a flanged cylindrical member.
