摘要： The device has a first metallic junction element affixed to a first pipe element and a second metallic junction element affixed to second pipe element. One of the junction elements is provided with an elastic lip cooperating with a frontal face provided on the other junction element.The element provided with an elastic lip has a nozzle element made of a metal or metallic alloy that is compatible from a welding point of view, with the material of the pipe element to which it is joined by welding, and cooperates with a tightening nut, and an end piece having an axial cross-section in the shape of a horizontal u so as to define the said elastic lip, the said end piece being made of a material that is different to that of the nozzle element so as to provide improved mechanical characteristics giving the elasticity that is necessary for the junction, and being affixed to the free end of the nozzle element by diffusion welding.
