ABSTRACT:
The clamping arrangement has a pair of elements which are provided with mating conical surfaces in the self locking range. The elements can be axially displaced relative to each other by axial clamping screws for clamping purposes. Auxiliary rings are provided between the elements and have through bores for the clamping screws. With the clamping screws removed, the auxiliary rings can be turned to align a tapped bore in one ring and an abutment surface in the other ring with a clamping screw so that this screw can be used for separating the clamped elements from each other.
