The invention relates to a device for clamping a workpiece (2) or tool comprising a hollow shaft cone (1) or similar, which comprises a tie bolt (4) which is mounted in an axially displaceable manner in the base body (3), in order to actuate a clamping head (6) which co-operates with clamping claws (5). The axial bearing of the tie bolt (4) is secured in a clamping position by self-locking without using the force of a clamping spring. |
