Abstract: A fluid connection device generally includes a male connector and a female connector configured to be co-inserted along an axis X, an elastically-deformable pin with a general U or C shape mounted on the female connector, the pin having one part passing through the female connector and configured to cooperate by elastic snap-fitting with the male connector, and a ring axially movable on the female connector between a pin release position and a locking position. In the device, the female connector may support elements that are radially mobile between a first radial position, for example, internal, whereby the ring is immobilized on the female connector, and a second radial position, for example, external, whereby the ring is released. The elements are generally configured to cooperate both with the male connector and the ring to release the ring when the pin is snap-fitted on the male connector.
