Abstract

The invention relates to a clamping device (1) having an inner pipe element (2) and an outer pipe element (3) which is concentrically arranged relative to the inner pipe element. Plate springs (4, 5, 6, 7, 8) which are arranged between these pipe elements twist the inner and outer pipe elements (2, 3) against one another in a direction of the pipe axis. These plate springs are arranged at a distance from one another and, as a result, allow for the absorption of increased tightening forces between the inner and outer pipe elements.
