ABSTRACT OF THE DISCLOSURE This invention discloses a hose coupling for use with a faucet, including an upright rod which is adapted for vertical motion in response to the water pressure in the hose. When the water pressure in the hose is normal, the upright rod movesto the upper limit of its range of travel, and slightly projects upward beyond a valve seat, pushing up a steel ball valve, and allowing the water to be discharged from the hose tip. If the water pressure in the hose in- creases abnormally, the upright rod retracts downward and allows the ball valve to fit on the valve seat. This invention provides an improved coupling when compared to the prior art devices in that it automatically shuts off the water supply if the hose is folded or flattened out result- ing in an abnormal increase in water pressure in the hose, and opens to resume the water supply when the water pressure in the hose returns to a normal level, in an improved and more efficient manner.
