Conical inner grooving of the intermediate element has conical flanks of an angle at the apex greater than the angle at the apex of the upper flanks of the receptacle and less than the angle at the apex of the corner flank. The resultants of the forces to which the intermediate element is subjected has a radial component. When pulled upward, the radial component is outward. Under a downward force, the radial component is inward.
