ABSTRACT:
A quick connector assembly for coupling a flexible hose or tube to a bore formed in a housing thereby to establish fluid communication between the interiors of the hose and bore, respectively, comprises an elongate tubular male insert having one end adapted to receive and retain the tube about its periphery. The other end of the male insert includes a contoured external surface defining an external locking flange, and a pair of axially-spaced external circumferential grooves for receiving a pair of O-rings which ultimately sealingly engage complementary cylindrical sections of the housing bore upon insertion of the connector assembly thereinto. Prior to its insertion into the housing bore, the connector assembly includes a garter spring which is radially collapsed about the male insert's contoured external surface by an encompassing annular spring guide. Upon inserting the connector assembly into the housing bore, the spring guide first seats itself against the housing and the garter spring is thereafter displaced by the locking flange from its radially-collapsed pre-insertion position within the spring guide down into the housing bore and, ultimately, into a locking groove formed internally of the housing bore. The garter spring thereafter further expands to allow the locking flange to pass therethrough and then radially contracts upon full insertion of the male insert into the housing bore to lock the connector assembly therein.
