Hose end fitting assembly

Abstract

A quick connect hose coupling assembly (10) for connecting a hose to an external device is disclosed. The assembly (10) includes a female coupling assembly (12) having an inner female tubular member (16). A housing member (14) is mounted thereon. The female member (16) includes a body portion (17) and a stem (20) adapted to be inserted into the inner channel (37) of a hose (38). The stem (20) includes an axial bore (21) adapted to convey a fluid therethrough. The stem (20) further includes a plurality of circumferential barbs (22). The stem (20) can also include an additional barb having a rotation resisting structure provided thereon to resist relative rotational movement between the stem (20) and a hose (38) into which the stem (20) is disposed. In a preferred embodiment of the invention, after the stem (20) is inserted into the end of the hose (38), a collar (40) of a plastic material is directly molded onto the portion of the hose (38) which is mounted over the stem (20), over a portion of the body (17) of the female member (18), and over a portion of the female housing member (14), thereby clamping the hose (38) to the stem (20), and affixing the collar (40) to the female member (18) and to the female housing member (14). Additionally, a novel detent clip (72) is inserted in apertures (64) provided in the housing member (14) to cooperate in engaging a circumferential flange provided on a male member (66), thereby retaining the male member (66) within the channel (18) of the female member (16).
