A female element (100; 200; 300; 400) of a quick connector, configured to connect to a male element, the female element comprising: • a body, which extends along an insertion axis and comprises: • a receiving volume for the male element, the receiving volume having a shape of revolution about the insertion axis and opening out of the body through a first mouthpiece, which is located in a transverse plane orthogonal to the insertion axis, the mouthpiece defining a front side of the female element, • radial openings, arranged in the body along a radial axis orthogonal to the insertion axis, which open into the receiving volume, • at least one latch (112; 312; 412), each latch being received in a respective radial opening and being movable in translation in relation to the body along the corresponding radial axis, between a first position, in which this latch penetrates into the receiving volume, and a second position, in which this latch does not penetrate into the receiving volume, each latch comprising a proximal face oriented on the side opposite the first mouthpiece, • an actuating ring (150; 250), arranged around the body coaxially to the insertion axis and movable in translation between a locked position and an unlocked position, in relation to the body along the insertion axis, • a return member, configured to return the actuating ring to its locked position. characterized in that the actuating ring (150; 250) comprises guide grooves (160; 260), which interact with pins of each latch (112; 312; 412) extending in a direction orthogonal to the radial axis of the corresponding radial opening, the guide grooves associated with each latch being geometrically carried by a guide plane (P160; P260) inclined in relation to the insertion axis, so that: - each latch is driven from its second position to its first position when the actuating ring is moved from its unlocked position to its locked position, and - each latch is driven from its first position to its second position when the actuating ring is moved from its locked position to its unlocked position. • a body, which extends along an insertion axis and comprises: • a receiving volume for the male element, the receiving volume having a shape of revolution about the insertion axis and opening out of the body through a first mouthpiece, which is located in a transverse plane orthogonal to the insertion axis, the mouthpiece defining a front side of the female element, • radial openings, arranged in the body along a radial axis orthogonal to the insertion axis, which open into the receiving volume, • a receiving volume for the male element, the receiving volume having a shape of revolution about the insertion axis and opening out of the body through a first mouthpiece, which is located in a transverse plane orthogonal to the insertion axis, the mouthpiece defining a front side of the female element, • radial openings, arranged in the body along a radial axis orthogonal to the insertion axis, which open into the receiving volume, • at least one latch (112; 312; 412), each latch being received in a respective radial opening and being movable in translation in relation to the body along the corresponding radial axis, between a first position, in which this latch penetrates into the receiving volume, and a second position, in which this latch does not penetrate into the receiving volume, each latch comprising a proximal face oriented on the side opposite the first mouthpiece, • an actuating ring (150; 250), arranged around the body coaxially to the insertion axis and movable in translation between a locked position and an unlocked position, in relation to the body along the insertion axis, • a return member, configured to return the actuating ring to its locked position. - each latch is driven from its second position to its first position when the actuating ring is moved from its unlocked position to its locked position, and - each latch is driven from its first position to its second position when the actuating ring is moved from its locked position to its unlocked position.
