Abstract

A detachable pipe joint and a method of joining a pipe to a valve, coupling, fitting or the like without requiring a special tool is capable of withstanding the higher fluid pressure typically generated within a larger diameter pipe. The pipe joint includes a retainer body defining a passageway for receiving a pipe, a retainer nut defining a through passageway coaxial with the passageway of the retainer body and the pipe, and a retaining ring positioned within an open end of the retainer body between the retainer body and the pipe. Securing means on the retainer nut engage securing means on the retainer body to compress the retaining ring in a radial direction when the retainer nut is advanced in an axial direction towards the retainer body. The retaining ring has at least one, and preferably a plurality, of inwardly extending projections to retain the pipe within the pipe joint.
