<p>A substantially C-shaped resilient coupling means (17) for mounting in a ring-shaped space, which is formed by two oppositely positioned grooves (13 and 14) in mutually engaged cylindrical faces (12) on two coaxial parts (10 and 11), has a shape different from a circular arc shape so that some parts of the coupling means will be positioned entirely in the one groove and other parts in the other groove. The force necessary for cutting the coupling means when the two parts (10 and 11) are to be disassembled, is hereby reduced greatly because of the established reduction of the cutting zone (21).</p> |
