ABSTRACT:
A joint for coupling small-diameter pipes, comprises a body including a cylindrical joint wall having a bore, and a cylindrical wall defining a stepped enlarged chamber in communication with the bore and receiving seals and a bushing behind the seals, the cylindrical wall having a rear end extending outwardly to provide a flange, and the bushing having an open end, a collar having a rear end extending inwardly to provide a locking wall and a front end extending inwardly to provide a engagement wall engaged with the flange, and a plurality of resilient retainer each having one end engaged with the open end of the bushing and the other end bent to a V-shape to provide a pawl. When coupling is effected, a bent portion of the retainer is brought into engagement with the locking wall, and the pawl is brought into engagement with an annular projection wall formed on one end of a pipe inserted into the enlarged chamber.
