A quick connector assembly (10) for coupling a flexible hose or tube (12) to a bore (14) formed in a housing (16) thereby to establish fluid communication between the interiors of the hose (12) and bore (14), respectively, comprises an elongate tubular male insert (18) having one end (20) adapted to receive and retain the tube (12) about its periphery. The other end (24) of the male insert (18) includes a contoured external surface (26) defining an external locking flange (28), and a pair of axially-spaced external circumferential grooves (30) for receiving a pair of O-rings (32) which ultimately sealingly engage complementary cylindrical sections (34) of the housing bore (14) upon insertion of the connector assembly (10) thereinto. Prior to its insertion into the housing bore (14), the connector assembly (10) includes a garter spring (36) which is radially collapsed about the male inserts (18) contoured external surface (26) by an encompassing annular spring guide (38). Upon inserting the connector assembly (10) into the housing bore (14), the spring guide (38) first seats itself against the housing (16) and the garter spring (36) is thereafter displaced by the locking flange (28) from its radially-collapsed pre-insertion position within the spring guide (38) down into the housing bore (14) and, ultimately, into a locking groove (50) formed internally of the housing bore (14). The garter spring (36) thereafter further expands to allow the locking flange (28) to pass therethrough and then radially contracts upon full insertion of the male insert (18) into the housing bore (14) to lock the connector assembly (10) therein. |
