A fluidic coupling comprising a male coupling element and a female coupling element able to fit in one another, the male element comprising: - a male body defining an inner conduit, - a valve, movable relative to the male body between an open position and a sealed closed position of the inner conduit of the male body, - a spring pushing the valve back toward its closed position, and the female coupling element comprising: - a female body defining an inner conduit along a longitudinal central axis and including at least one sealing gasket, - a piston extending along the longitudinal central axis, - a slide valve mounted around the piston and movable relative to the female body along the longitudinal central axis between a closed position, in which the sealing gasket of the female body cooperates with the slide valve and the slide valve cooperates sealably with the piston, and a retracted open position of the inner conduit of the female body, in a coupling phase between the male element and the female element, the male body pushes the slide valve back toward its open position and the piston pushes the valve back toward its open position, the fluidic coupling being characterized in that: - the piston is mounted with the possibility of movement relative to the female body along the longitudinal central axis between a rear position and a forward position, - the female element comprises at least one lever for converting the movement of the slide valve into movement of the piston, - during the coupling phase: from the closed position of the slide valve to an offset position of the slide valve, in which the male body cooperates with the sealing gasket of the female body, the or each lever is disengaged from the slide valve and/or the piston, and the piston is in the rear position; from the offset position of the slide valve to the open position of the slide valve, the lever is engaged with the slide valve and with the piston, and moves the piston toward its forward position; - in the coupled configuration, the piston is in its forward position and extends partially in the male body, a fluid passage being formed around the piston in the male body. - a male body defining an inner conduit, - a valve, movable relative to the male body between an open position and a sealed closed position of the inner conduit of the male body, - a spring pushing the valve back toward its closed position, - a female body defining an inner conduit along a longitudinal central axis and including at least one sealing gasket, - a piston extending along the longitudinal central axis, - a slide valve mounted around the piston and movable relative to the female body along the longitudinal central axis between a closed position, in which the sealing gasket of the female body cooperates with the slide valve and the slide valve cooperates sealably with the piston, and a retracted open position of the inner conduit of the female body, - the piston is mounted with the possibility of movement relative to the female body along the longitudinal central axis between a rear position and a forward position, - the female element comprises at least one lever for converting the movement of the slide valve into movement of the piston, - during the coupling phase: from the closed position of the slide valve to an offset position of the slide valve, in which the male body cooperates with the sealing gasket of the female body, the or each lever is disengaged from the slide valve and/or the piston, and the piston is in the rear position; from the offset position of the slide valve to the open position of the slide valve, the lever is engaged with the slide valve and with the piston, and moves the piston toward its forward position; from the closed position of the slide valve to an offset position of the slide valve, in which the male body cooperates with the sealing gasket of the female body, the or each lever is disengaged from the slide valve and/or the piston, and the piston is in the rear position; from the offset position of the slide valve to the open position of the slide valve, the lever is engaged with the slide valve and with the piston, and moves the piston toward its forward position; - in the coupled configuration, the piston is in its forward position and extends partially in the male body, a fluid passage being formed around the piston in the male body.
