Pipe joint for connecting a pipe having a small diameter

摘要

A pipe joint for connecting a pipe having a relatively small diameter includes a generally cylindrical main body having an axial bore in which an end portion of the pipe and a plurality of seal rings surrounding the end portion of the pipe can be fitted. The main body has a tubular extension defining a connector for another tubular member to be connected to the pipe by the joint and having an axial bore which can be connected with that of the pipe. The main body also has a plurality of pawl projections or a shoulder on its outer peripheral surface. The pipe has a radially outwardly projecting wall portion near its end portion. A generally cylindrical cap has an end wall portion provided therethrough with a central opening through which the pipe can extend into the main body, and a plurality of resilient arms projecting from its end wall portion. Each arm has adjacent to its free end a hole in which one of the pawl projections on the main body can be received, or a pawl projection which is engageable with the shoulder on the main body. The end wall portion of the cap is engageable with the radially outwardly projecting wall portion of the pipe to hold the pipe in its properly connected position.
