ABSTRACT:
A coupler for coupling an end of a hose to a mating end of a faucet or another hose. In the first embodiment, the female end of the coupler is mechanically locked in sealing engagement with a male end by simply translation thereof by means of wedges and an outer retaining sleeve. In a second embodiment, hydraulic pressure provides the final seal, with the female end being a spring split-ring locked and compressed by means of an outer locking sleeve, which outer locking sleeve is released by squeezing it in order to deform it. A third embodiment combines the first and second-embodiments.
