The joint has two tubular parts (8, 9) interposed between a frame and a door or window. The part (8) is integrated to a joint part (5) having U shaped cross section that covers a projecting part of the frame. The tubular part (8) has a wall whose thickness varies along the length of the joint such that the pressure exerted by the joint on the door or the window is varied. |
