Abstract
A female element of a quick connection provided with a closure valve, wherein the opening of the valve is controlled by a reaction force exerted by an O-ring disposed in an inner housing of a body of a male connection element adapted to be fitted in the female element. The reaction force results from the abutment of the valve on the O-ring when the male and female elements are coupled together. Upon the failure of the O-ring, the valve is not displaced so that the risks of leakages are eliminated.
