Abstract
A device for temporary fluidic coupling between a source of pressurized fluid and a user member includes a supplied end-fitting and a supply end-fitting, at least temporarily placed face to face in a given longitudinal direction and connected respectively to the user member and to the source of pressurized fluid, wherein the supply end-fitting includes a retractable seal in the form of a longitudinal tubular piston which, when it is urged by the pressurized fluid, passes from a retracted rest position to an active position in which it is applied against a transverse annular face of the supplied end-fitting to connect the respective pipes in a sealed manner, and which resumes its retracted rest position when it is no longer urged by the pressurized fluid.
