QUICK-CONNECT HOSE COUPLING An apparatus for establishing a quick-connect fluid-tight coupling together of hose sections or the like. A pair of identical couplings are provided each interconnected to and terminating a respective hose section and adapted to be aligned along a common co-axis in mutual sealing engagement. Each coupling includes a body member having a circular seal face disposed in a plane perpendicular to the axis. Means are provided on each body member for releasably sealing the seal faces together in fluid-tight engagement by rotation of the body members in opposing directions about the axis. Each body member includes a locking assembly mechanism for automatically locking the respective body members together upon make-up to prevent further relative rotation in either direction or separating movement in the axial direction. Each locking mechanism is releasable whereby, upon disengaging rotation of the body members in the opposite direction from make-up, the locking assemblies of each body are re-armed in preparation for a next make-up. The locking mechanisms are aligned about the common axis whereby in an un-armed position, the respective body members are thereby prevented from being joined together. |
