ABSTRACT:
A quick connect hose coupling assembly (10) of the type for joining fluid carrying conduits, including a female member (12) and a male member (40). The female member (12) has an annular portion (20) and a plurality of slots (21) defining fingers (22). The fingers (22) extend longitudinally from the annular portion (20) to a distal end (23). The male member (40) is inserted into a bore (50) defined by the female member (12). A flange (54) on the male member (40) engages a groove (52) in the female member (12) for limiting longitudinal movement of the male member (40) with respect to the female member (12) when the male member (40) is inserted in the bore (50) of the female member (12). A locking ring (64) is disposed in the groove (66) on the fingers (22) to prevent both outward radial movement of the fingers (22) and relative longitudinal movement between the male (40) and female (12) members. A sealing boot (58) is integral with the locking ring (64) and extends about the distal end (23) of the fingers (22). The boot (58) engages the male member (40) and an inward tapered surface (48) of the female member (12) to prevent contamination from entering the interior of the female member (12).
