A coupling device includes a tubular body () having a plastics material portion provided with an anchor member () for anchoring the tubular body in a first duct, the anchor member being made of metal. The anchor member is secured to a metal support element () that is covered at least in part in a layer of plastics material () compatible with the plastics material of said tubular body portion and that is connected to said portion by local welding of said portion with said layer. A method of fabricating such a coupling device.

Connecting device with welded body

An anchor washer for anchoring a first element and a second element in relative engagement, includes an annular portion from which there extends at least one tooth that is inclined relative to a central axis of the annular portion, the annular portion being designed for mounting on the first element, and the tooth having two side faces between which there extends a rubbing surface for being oriented substantially towards the second element, the surface being connected to the side faces via coupling portions, the tooth being shaped so that at least one of the coupling portions is set back from at least a portion of the surface so that the coupling portion is kept at a distance from the second element. A coupling device including such a washer is also disclosed.

Non-aggressive anchor washer

A ball coupler having a longitudinal axis and including a male tubular endpiece; a female tubular endpiece; and a tubular sleeve extending the female endpiece and presenting slots for forming a cage for retaining balls for blocking the male endpiece in the female endpiece. A grip is coaxial about the sleeve and mounted to turn about the longitudinal axis of the coupler between at least two angular positions relative to the sleeve, the grip having a housing for each ball. A resilient return device urges the grip into its first position, including in the grip, a ring that is constrained to turn with the grip and that is movable axially relative thereto.

Ball coupler

An instantaneous connection device includes a tubular body and a tight element which is used to hold the end of a line in the body and includes a holding element arranged to receive the end of the line and a cam element arranged between the body and the holding element and used to move the holding element from a free state into a state wherein it grips the end of the line when it is axially displaced in the tubular body between a first position and a second position. The holding element includes two jaws independently mounted in the body so as to slide between the two positions, and the cam element includes two transversal pins that are fixed to the jaws or body so as to slidingly co-operate, with transversal surfaces fixed to the body or the jaws and inclined in relation to the sliding direction.

Instantaneous connection device

An instantaneous connection device includes a tubular body, a tight element used to hold the end of a line in the body and includes an elastically deformable annular sealing element and a holding element that are arranged to receive the end of the line, a cam member for moving the holding element from a free state into a state wherein it grips the end of the line when it is axially displaced in the tubular body from a first position to a second position, and an elastic member for bringing the holding element back towards its second position. The sealing element is mounted between a radial shoulder of the body and a radial face of the holding element. The radial shoulder and the radial face are provided with reciprocal reliefs for laterally coming into contact with the annular sealing element.
