Abstract

The invention concerns a clamping device for connecting a tool head, which has a cylindrical or at least part-conical bore, with a tool holder which has a matching pin, the tool holder and the tool head being clamped together by means of a shaft designed to rotate about its longitudinal axis. In order to be sure of preventing the shaft from becoming unintentionally unclamped when in the clamped condition, the shaft is locked, in the direction of rotation necessary to undo it, by means of a pawl stop, the locking mechanism being released by an externally operated machine element.
