This female quick-connect coupling element for releasably joining together pipes for pressurized fluid is equipped with a fluid flow duct (44) and with a valve (200) for controlling the flow of the fluid through the duct, the valve having a first piston (50) and a second piston (52) that are mounted to move along the same axis (Y-Y′) relative to a body (40) of the female element (A). The first piston is suitable for co-operating directly or indirectly with a seat (47) formed by the body of the female element, so as to close the valve (200), while the first and second pistons are interconnected via mechanical link means (142, 144, 152, 154), and each of said pistons defines one of two opposite surfaces (502, 522) in contact with the fluid when the valve (200) is open. The mechanical link means (142, 144, 152, 154) between the first and second pistons (50, 52) are disposed outside the fluid flow duct (44).
