摘要： A device operative to generate a pre-tension between two elements which are to be mounted in spaced relation on an axle is disclosed. The device includes a first ring (1) and a second ring (2) configured to generate upon compression a substantially constant pre-tensioning force as the result of the first ring being pressed axially into the second ring against the force of a radial expansion of a portion of the first ring which is superimposed onto the second ring. The second ring has an annular notch (7) which is defined in radial directions between an inner wall (9) and an outer wall (8) and which opens towards the first ring which is insertable into the notch, wherein the radius to the outer wall (8) of the notch is determined such that the outer wall prevents further radial expansion of an expanded portion of the first ring.
