ABSTRACT:
An adapter for connecting a nozzle or similar attachment to the threaded end of a garden hose or the like has a body with an internally threaded end connectable to the hose threads and a spring loaded retractable coaxial sleeve which extends over and protectively covers the external threads at the other end of the body to which the nozzle is connectable. When the nozzle is to be connected to the adapter, the sleeve is withdrawn over the body, compressing the spring and exposing the external threads to the nozzle. When the nozzle is disconnected, the spring expands and returns the sleeve to its protective position surrounding the threads.
