Claim Text:
1. A female quick coupling element configured to cooperate, by press fitting along a press fitting axis, with a male quick coupling element and comprising: a body centered on a longitudinal axis, defining a duct for the passage of fluid and comprising, at its distal end, a flat front face, a relief valve comprising a valve lodged in the duct for the passage of fluid and mobile along the longitudinal axis in relation to the body, between a closed position of the relief valve, abutting against a seat of the relief valve, and an open position of the relief valve, separated from the seat, a manoeuvring ring mounted slidingly around the body and defining, at a distal end of said manoeuvring ring, a mouth for receiving the male element, with the ring provided with one relief configured for engagement with a corresponding relief of the male quick coupling element, wherein the female coupling element further comprises a safety ring mounted around the body, radially inside the manoeuvring ring, the safety ring being mobile axially in relation to the body between a first position, where the manoeuvring ring and the safety ring are integral in rotation about the longitudinal axis, and a second position where the manoeuvring ring can rotate about the longitudinal axis in relation to the safety ring, a movement transforming means for transforming, when the safety ring is in its second position, a movement of rotation of the manoeuvring ring about the longitudinal axis and in relation to the safety ring, into a movement of axial translation of the body in relation to the manoeuvring ring.
