Fluid connection device

A fluid connection device, comprising:

• a male connector and a female connector, which are configured to be fitted one inside the other along an axis so as to produce a fluid connection,
• at least one annular seal carried by one of the connectors and configured to cooperate with the other of the connectors in order to ensure a seal between the connectors,
• the connections connectors being configured to be fastened to each other by resilient snap-fastening and to retain after fastening at least one degree of freedom with respect to each other,
• wherein the connectors are fastened together by a double fastening by resilient snap-fastening and by bayonet, the resilient snap-fastening being configured to be irreversible without deterioration so that, after fastening, the device cannot be dismantled without deterioration, and wherein the male connector comprises members configured to cooperate both by resilient snap-fastening and bayonet effect with complementary elements of the female connector,
• wherein the members project from an outer annular surface of the male connector,
• wherein each of the members comprises a radially outer surface comprising a slope inclined in the circumferential direction with respect to the axis, and
• wherein the radially outer surface comprises a first circumferential end located on a circumference of a first diameter and a opposite second circumferential end located on a circumference of a second diameter, said second diameter being smaller than said first diameter, each of the members comprising an abutment side surface located on the side of said first circumferential end.

• wherein the members project from an outer annular surface of the male connector,
• wherein the male connector further comprises pads projecting from its outer annular surface and configured to slidingly cooperate with an inner annular surface of the female connector,
• and wherein the pads and the members are located substantially in the same plane transverse to the axis, the number of pads being equal to the number of members and each pad being disposed between two adjacent members.

• wherein the female connector comprises an opening for engaging the male connector, this opening being delimited by a peripheral annular edge comprising axial windows for engaging the members of the male connector by axial translation,
• and wherein each window is connected to a first circumferential slot adapted to receive the corresponding member during a circumferential movement of the male connector in the female connector.
