  • Patent number: 4105226
    Abstract: A snap-in fitting includes male and female connector elements which are connectable to fluid conduits. The male connector element is insertable within a socket of the female connector element and is retained therein by a coupling ring. The coupling ring includes an integral base portion, collar portion and locking portion. The collar portion is seated within a retaining channel of the male connector element, and the locking portion lockingly abuts within a locking groove of the socket. The collar portion includes annular surfaces which converge from the base portion. The locking portion extends outwardly at an angle from the base portion and includes annular surfaces which diverge from the base portion. An undercut is formed at the juncture of the locking portion with the base portion, to maintain the pivot point of the locking portion adjacent such juncture. An O-ring mounted on the male connector element sealingly engages a wall of the socket.
