Female quick-connect coupling element for the detachable connection of two pressurised fluid pipes, this female element being able to receive by fitting, according to a longitudinal axis (X-X') of this female element and in an insertion channel located on a front side of the female element, a male coupling element, this female element comprising: - a body through which passes a conduit for the circulation of fluid, - balls for locking the male element in a coupled configuration, with these locking balls being positioned in radial housings of the body and able to protrude radially in the insertion channel, - an actuating member (90; 80) mobile in translation according to a longitudinal axis (X-X'; X80) between a first position, in which the male element is locked in the female element in coupled configuration, and a second position, in which the male and female elements are in uncoupled configuration, during a disconnection manoeuvre of the male element and of the female element, - an intermediate locking ring, mobile in axial translation between a rear position, in which an internal wall of the intermediate ring maintains the locking balls protruding in the insertion channel in coupled configuration of the coupling, and a front position of the front side of the female element, in which the locking balls are free to be pushed back opposite the longitudinal axis (XX') of the female element in order to no longer protrude in the insertion channel, under the action of the actuating member (90; 80) during the disconnection manoeuvre, this female element being characterised in that it comprises means (98; 94) of locking in rear position of the intermediate ring in coupled configuration of the coupling and in that the unlocking of the intermediate ring towards its front position is triggered by the clearing of the actuating member (90; 80) towards its second position. - a body through which passes a conduit for the circulation of fluid, - balls for locking the male element in a coupled configuration, with these locking balls being positioned in radial housings of the body and able to protrude radially in the insertion channel, - an actuating member (90; 80) mobile in translation according to a longitudinal axis (X-X'; X80) between a first position, in which the male element is locked in the female element in coupled configuration, and a second position, in which the male and female elements are in uncoupled configuration, during a disconnection manoeuvre of the male element and of the female element, - an intermediate locking ring, mobile in axial translation between a rear position, in which an internal wall of the intermediate ring maintains the locking balls protruding in the insertion channel in coupled configuration of the coupling, and a front position of the front side of the female element, in which the locking balls are free to be pushed back opposite the longitudinal axis (XX') of the female element in order to no longer protrude in the insertion channel, under the action of the actuating member (90; 80) during the disconnection manoeuvre, this female element being characterised in that it comprises means (98; 94) of locking in rear position of the intermediate ring in coupled configuration of the coupling and in that the unlocking of the intermediate ring towards its front position is triggered by the clearing of the actuating member (90; 80) towards its second position.
