1. A connector element, for a quick connect coupling of a fluid pipe to a terminal, the terminal having an interface with a cylindrical enclosure, the connector element comprising:
a body designed to be secured with the fluid pipe and delimiting an inner passage for the fluid, the inner passage extending along a fitting axis of the connector element, wherein the body comprises a conical portion, centered on the fitting axis;
a bush, which is translatable relative to the body along the fitting axis;
a first elastic return member, which applies a first elastic return force on the bush, relative to the body, along a forward direction;
clamping pads, each clamping pad being received in a respective opening belonging to the bush, the clamping pads being moved in translation radially relative to the bush, within their respective opening, by mechanical cooperation of the clamping pads with the conical portion, between:
a radial withdrawn position of the clamping pads, so that the clamping pads are remote from the interface of the terminal, and
a radial clamping position of the clamping pads, so that the clamping pads cooperate mechanically with the interface of the terminal;
a bearing ring, which is translatable relative to the body along the fitting axis and which comprises:
a circumferential face, by means of which the bearing ring is in fluid-tight radial contact with the body, and
a front face perpendicular to the fitting axis; and
a second elastic return member, which is formed by a spring and which applies a second elastic return force in the forward direction on the bearing ring to place the bearing ring in fluid-tight contact with the terminal by means of the front face.
