Abstract
Quick coupling for a hose (,), comprising a tubular end fitting (,) which has an axial tapering surface (,) that can be pushed at least partially into the end of the hose (,); a clamping ring (,) mounted to rotate on the end fitting (,) and having, at its end facing the tapering surface, an axial opening (,) with a diameter that is between the extreme diameters of the tapering surface (,); and guide means (,) provided on the end fitting (,) and on the ring (,), arranged so that rotation of the ring is accompanied by an axial movement thereof; by virtue of which, when the ring is tightened onto the end fitting, its axial movement along the tapering surface tightens it onto the said tapering surface with the end of the hose being tightened and locked against the tapering surface.
