A female element of a quick-coupling, configured for being coupled to a hose, the female element comprising:
- a body:
- which extends along a longitudinal axis and which defines a volume for receiving the hose, the receiving volume having a shape of revolution about the longitudinal axis and jutting from the body through a mouth, the mouth defining a front side of the female element,
- which comprises an abutment surface, which is located in a plane orthogonal to the longitudinal axis and which is oriented towards the front of the female element, the abutment surface delimiting the volume for receiving a rear side of the female element, the rear side being opposite to the front side, one nipple:
- which is rigidly attached to the body of the female element and which extends into the receiving volume from the abutment surface,
- which comprises a hollow body having a shape of revolution about the longitudinal axis, the hollow body defining a channel which emerges at the front side of the female element and into a passage provided in the female element on the rear side,
- which comprises an external surface,
- wherein the female element further comprises:
- at least one radial opening, each radial opening being provided in the body of the female element along a guide axis radial to the longitudinal axis, each radial opening jutting into the receiving volume,
- at least one lock, each lock being received in a respective radial opening and being movable in translation with respect to the body along the corresponding guide axis between a first position, wherein the lock penetrates into the receiving volume, and a second position, wherein the lock is further away from the longitudinal axis than in the first position, each lock comprising an internal surface for clamping the hose, oriented towards the longitudinal axis opposite the external surface of the nipple,
- a return member configured for returning each lock to the first position thereof, and
- an operating ring, which is arranged around the body coaxially with the longitudinal axis and which is movable in translation with respect to the body along the longitudinal axis between a locking position and an unlocking position,
- and wherein:
- each lock comprises pins, each extending along a direction orthogonal to the corresponding guide axis and orthoradial to the longitudinal axis,
- the operating ring comprises guide grooves which cooperate with the pins of each lock, the guide grooves associated with each lock being geometrically supported by a guide plane inclined with respect to the longitudinal axis, so that:
- each lock is driven from the second position thereof to the first position thereof when the operating ring is moved from the unlocking position thereof to the locking position thereof, and
- each lock is driven from the first position thereof to the second position thereof when the operating ring is moved from the locking position thereof to the unlocking position thereof.
