Abstract: 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.

Abstract: A coupling formed of a tubular body defining an internal channel. The body is formed of a first part for connecting the channel to a circuit element and a second part defining a housing for a pipe end, the first and second parts including mutually engaged end portions, wherein the housing extends into the end portion of the second part and the end portions include facing openings for receiving a clip element for securing the parts to each other. The opening of the second part opens into the housing and the clip element has a locking portion that is elastically deformable from a retaining state to a free state for extracting the clip element. The clip element projects into the housing such that the pipe end prevents the locking portion from deforming to its free state and being extracted.

Abstract: Device for adjusting a height of a seat, including at least one actuator connected to at least one source of power via at least one control valve having at least one control member for controlling the pressurizing of the actuator and at least one control member for controlling the exhausting of the actuator, the device including a cam associated, on the one hand, with at least one means of driving as a function of a variation in height of the seat, and, on the other hand, with the valve control members, the cam being configured to have at least one neutral position in which it actuates no control member, and at least two active positions about the neutral position, these respectively corresponding to a pressurizing of the actuator when the cam has pivoted about the neutral position in a direction corresponding to a reduction in the height of the seat and to an exhausting of the actuator when the cam is pivoted about the neutral position in a direction corresponding to a raising of the height of the seat, the

Abstract: An anchor device for anchoring an element such as a coupling in an opening in a wall the device including a sleeve for receiving the element, the sleeve being externally provided with a shoulder for bearing against a first face of the wall, and with an anchor member facing the shoulder having a portion that is resiliently movable between a laterally projecting position and a retracted position. The anchor member is a frustoconical ring received in a groove in the outside of the sleeve, the ring having larger end facing the shoulder with a sloping surface which forms the resiliently movable portion and which bears in the laterally projecting position against a zone of intersection between a side surface of the opening and a second face of the wall.

Abstract: The rigid coupling device includes a closure valve extended by a retractable sliding stop member of general tubular shape made from elastically deformable material, having at least one outward radial projection forming a stop against a corresponding inward radial projection of a movable interior body that contains the valve. The stop member has an open end opposite the opening of the cylindrical cavity of one end connecting to the conduit. Simultaneous withdrawal of the interior body and of the valve into the interior body has the effect of causing this open end to contract, forcibly inserting it into the cylindrical cavity of the connecting end in such a manner as to overcome the stop.
