Provided in one leg of the slide is a pin that is mounted in the leg in such a way that it is displaceable at right angles to the slide. A spindle is provided for shifting the pin between two end positions, namely a first end position where the pin extends into the teeth of the fastener, and a second end position where the pin releases the teeth.
