One of the end portions has a smaller cross-section than the central portion and is provided with longitudinal lugs each forming a cam and terminating in a bevelled tip, said lugs being disposed in the line of extension of the ridges of said polygonal cross-section. Each face of the other end portion is provided with a V-shaped ramp for supporting said bevelled tips and guiding said lugs towards the summits of said polygonal cross-section.
