Abstract: A quick disconnect and release hose couplings is disclosed where the socket will disconnect and release from a plug if the hose connected to the hose coupling is pulled with sufficient force. A quick disconnect female socket used in the hose coupling includes a body portion and a movable sleeve. The hose coupling includes an end conduit that is adapted for coupling to a hose. The end conduit is connected to an intermediate conduit, and the intermediate conduit is connected to the body portion of the socket. The hose is in fluid communication with the socket through the end conduit and intermediate conduit. The intermediate conduit also permits the end conduit to move relative to the body portion. A mechanical coupling is attached to the end conduit and to the sleeve of the socket such that when the end conduit moves relative to the body portion the mechanical coupling moves the sleeve relative to the body portion.
