A coupling device for mounting onto the spout of a faucet is disclosed. The device is connected or connectable to a hose and includes an elastomeric sleeve and a clamp assembly. The clamp assembly includes a housing and a pressure applying member. The housing has a cavity holding the sleeve between a back wall and the pressure applying member. The sleeve receives the externally threaded spout. The pressure applying member is movable to a closed position to compress the sleeve tightly about the spout to releasably secure the device to the faucet. The pressure applying member is also movable to an open position to release the spout from the sleeve. Also disclosed is a cap device for releasably sealing an externally threaded mouth of a bottle or other hollow vessel and making use of an elastomeric sleeve and a clamp assembly similar in many respects to the coupling device.

A tube quick-release assembly includes an outer socket and an inner plug. The inner plug is movably inserted in the outer socket. An upper portion of the outer socket is formed with two opposing engaging openings. An engaging buckle is fitted on the inner plug. The engaging buckle is provided with two opposing engaging legs having hooks and flaring outward. The hooks of the engaging buckle radially engage with the two engaging openings of the outer socket to realize a quick connection of tubes. The two hooks of the engaging buckle can be pressed inward to realize a quick disconnection of tubes.

An embodiment of a fluid valve includes a substantially flat face plate, a receptacle, a cavity, and a drain assembly. The receptacle is disposed in the face plate and has at least one protrusion each configured to engage a respective one of at least one groove of a valve-opening-and-fluid-dispensing device. The cavity has a top end in fluid communication with the receptacle, and has a bottom end. And the drain assembly has a top end in fluid communication with the bottom end of the cavity, has a bottom end, and is configured to allow fluid to drain from the cavity in response to the valve-opening-and-fluid-dispensing device being absent from the receptacle.

An embodiment of a fire-suppression water-intake valve includes a receptacle and a valve assembly. The receptacle is configured to receive a sprinkler head. And the valve assembly is configured to close in response to removing a sprinkler head from the receptacle, and is configured to open in response to installing a sprinkler head in the receptacle. Such a fire-suppression water-intake valve can allow quick and easy removal and installation of a fire-suppression sprinkler head without shutting a water supply to the valve.

A sprayer attachment with a faucet sleeve for securing to a tub faucet. The sprayer attachment includes a hose having a spray head at a first end and a faucet attachment disposed at an opposing second end, wherein the faucet attachment can be inserted within or around a faucet opening to allow water to pass through the hose to the spray head. The faucet sleeve extends from the second end of the hose, wherein the sleeve is movable between a non-use configuration and an in-use configuration. In the non-use configuration, the sleeve is rolled towards the first end, exposing the faucet attachment. In the in-use configuration, the faucet attachment is inserted within or around the faucet opening and the sleeve is unrolled, concealing the faucet attachment. The sleeve is flexible and elastic to secure around a length of the faucet.
