Claim:
1. A tool holder comprising: a collet configured to be clamped to the shank of a tool; and a pull-out protection configured to secure the tool against being pulled out of the collet, the pull-out protection including a wedge-shaped protection element having force-transmission surfaces configured such that pull-out forces acting on the tool are transmitted to the collet, wherein the protection element is mounted so as to be movable relative to the collet, wherein the protection element is, due to its wedge-shape, configured to be, when in a radially inner engaged position with the tool, clamped to the tool and to the collet so as to be self-locking, wherein clamping forces of the collet acting on the tool are not influenced by the protection element, and wherein the protection element only has a function as a blocking element when the pull-out forces acting on the tool exceed the clamping forces of the collet acting on the tool.
