ABSTRACT:
This invention relates to a hose coupling having mounted thereon a leaf spring locking member of such a configuration that the free end is so disposed that it constitutes a stop which is shiftable by the guard arm of the other one of a pair of hose couplings out of the pathway of this guard arm on the other one of the hose couplings as the one hose coupling and the arm thereon are rotated toward the fully coupled position of the pair of hose couplings. The configuration of the stop is such that the resiliency of the leaf spring locking member, upon the pair of couplings reaching their fully coupled position in which the arm passes out of contact with the stop, shifts this stop to a position in the pathway of the arm thereby preventing unwanted uncoupling of the pair of fully coupled hose couplings until the leaf spring is manually deflected to shift the stop out of the pathway of the guard arm.
