An improved quick-disconnect hose coupling comprising a female coupling half having a ball valve designed with positive interlocking means for retention of a male coupling half in a receptacle formed therein. The ball valve is enclosed in a housing and is arranged to be pivotable therein about an axis, such that the male coupling half communicates with a bore hole in the other end of the ball valve. Pivoting movement of the ball valve provides a flow connection by bringing the bore hole into communication with a hose connector element retained in the other end of the housing, while interlocking pins contained in the ball valve mechanically engage the male coupling half in the receptacle. In one embodiment, a releasable latch engages a contoured slot in the housing for providing positively defined valve operating positions, such that the mechanical connection is completed prior to and separate from the flow connection. In another embodiment, the latch is provided by a pair of beads each of which is seated within one of a pair of apertures formed on opposite sides of the ball valve walls. Each latching bead is retained against a notched fastener on a respective side of the ball valve. A movable locking sleeve disposed within the ball valve blocks the latching beads from inward movement in the apertures, thus preventing ball valve rotation. Upon depression of the male coupling half in the locking sleeve, the blockage is removed and the valve may be rotated, releasing the interlocking pins and allowing removal of the male coupling half. The novel design offers increased safety and simplicity of operation.

A quick-disconnect hose coupling device comprising: a housing having an opening at an end thereof for retention of a hose connector element therein; a ball valve body disposed in said housing and being pivotable therein about an axis, said ball valve body having formed therein a receptacle for insertion of a male coupling half through an opening in an opposite end of said housing; and positive interlocking means contained within said ball valve body proximate said pivot axis and cooperating with said housing to allow insertion of said male coupling half in said receptacle when said ball valve body is pivoted to a first position whereat it does not communicate with said connector element, said ball valve body being pivotable to a second position whereat said positive interlocking means retentively engages said male coupling half in said receptacle prior to alignment with said connector element for communication therewith, said engagement being releasable when said first position is reestablished.
