Abstract
A quick-coupling fitting for pipes comprises a female element and a male element that can be coupled together, formed by fixed parts and axially sliding parts. The fitting is provided with a valve apt for intercepting a communication port between a conduit and a passage port for the fluid in the initial stages of the coupling action and for opening it in the final stages of the coupling action. A seal of a fixed internal casing is covered by a sliding bush whatever is the axial position assumed by the bush during the initial and final stages of the coupling action.
