Abstract

The invention relates to a holding clamp (17, 17') consisting of a device (3) for locking and/or unlocking a tool (1) head (8). The holding clamp (17, 17') extends along an overall axis of elongation (A3) of the holding clamp (17, 17'). The holding clamp (17, 17') includes a slide ramp (27, 27') for the tool (1) head (8). The slide ramp (27, 27') forms an angle (a) with the overall axis of elongation (A3), which is between 0° and 45°.
