Abstract

The high pressure coupling for attaching the hose of a spray cleaner to a fitting (2) on the machine comprises a socket (1) which screws on to the fitting and has an outlet (6) at the top. A sliding valve (4) inside the socket seals the outlet. A sleeve (3) is fitted on to the socket. This has a pin (16) inside it which pushes the slide down as it is fitted and opens the outlet.
