CLAMPING COMPONENT AND TOOL HOLDER

The invention relates to a clamping component comprising a locking pin which can be moved between a first and a second position and is provided with a tool holding region formed between the ends of the locking pin. In the first position, the tool holding region protrudes into a tool receiving bore of the clamping component, while in the second position the locking pin does not protrude into the tool receiving bore. The locking pin is always positioned on the clamping component in both the first and the second position, thus making the improved pull-out stop particularly easy to handle and preventing loss. The locking pin can be moved (continuously) between the first and second position, the tool holding region of the locking pin in the first position preventing the tool from being pulled out and twisted out of the tool receiving bore.
