A coupling element of a fluid circuit. The coupling element includes a tubular body externally provided with an annular shoulder in which a groove is provided having an end wall flanked by an outer side and by an inner side so as to receive an annular seal designed to bear against a surface surrounding an inlet orifice of a channel of a member to which the element is designed to be coupled. The body defines at least one passage for bringing the fluid into the groove so as to push the seal back against the outer surface of the groove, and against the surface surrounding the inlet orifice of the channel.
