Abstract
This female quick-coupling element for a quick-connect coupling is able to cooperate with a male coupling element. A control ring is able to move in translation along a longitudinal axis between a first position and a second position. A blocking member prevents translation of the control ring as far as its second position. An element for the elastic return of a piston, integral in transverse movement with the blocking member, to its internal position is mounted in a housing of the first coupling element situated outside the housing of the piston, and fluidically isolated from the fluid-flow conduit. The first coupling element comprises transmission means, disposed between the return element and the piston, to return the piston to its internal position.
