Abstract: 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 moves to 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 increases abnormally, the upright rod retracts downward and allows the ball valve to fit on the valve seat.

Abstract: A clipping hanger includes a rod having at one end a hook and at the other end a ball, opposing gripping plates integrally connected to each other by a U-shaped elastic member having an opening at the center thereof, a squeeze arm fixed to each of the gripping plates, a leaf spring bent between the squeeze arms and connected at each end to each of the squeeze arms so as to urge the gripping plates against each other. The ball of the rod is rotatably socketed in the opening of the U-shaped elastic member, and is held by the bent portion of the leaf spring fitted in the opening.
