Abstract
A quick-release coupling includes a male part and a female part. The female part has a valve stem attached to an inner tubular body so as to define a number of flow channels, and an outer body that houses a pair of sliders. The female part also has an intermediate sleeve that slides inside the outer body and is attached to the inner tubular body. The outer body has an inner stop shoulder which defines an extended position of the sleeve. A sealing device, movable by the pressure of a fluid present in the female part, is present at the rear between the sleeve and the outer body. The sleeve is stressed from the rear by a pressure spring. The outer body is locked to and released from the sleeve.
