Abstract

A clamping device includes a first clamping plate and a second clamping plate, the first clamping plate being rotatable between a released position and a clamped position in relation to the second clamping plate. The clamping device further includes a rolling body which establishes contact between the first and second clamping plates. The second clamping plate includes a clamping ramp with a contour for the rolling body so that when the clamping plates are rotated in relation to each other, the space between the clamping plates changes. The first clamping plate has a surface which forms a plane on which the rolling body rolls from the released position to the clamped position.
