Abstract: In a clamping fixture (1) for clamping a workpiece (10), wherein the clamping fixture has at least one clamping device (4) and at least one guiding device working together with the clamping device, wherein the clamping device can be moved axially along the guiding device, wherein the clamping device has a radial profiling (6), wherein the guiding device has an opposing profiling (7), corresponding to the radial profiling of the clamping device, and wherein, when there is an axial movement of the profiling of the clamping device along the opposing profiling of the guiding device, the clamping device is forced in a substantially radial direction, and thereby clamps the workpiece in place, less susceptibility to wear, and consequently a longer operational service life, is obtained by the clamping device being formed in at least two parts.
