The invention relates to a device making it possible to hold a circular rack of a chuck together with a bevel-geared key for locking tools without damaging the rack and the key. Opposite the sleeve, a handle makes it possible to hold the assembly correctly positioned on the snout (tip) of the chuck in order to obtain good clamping of the assembly. It consists of a sleeve 1 having an orifice on the side 2 for the passage of the bevel-geared key 3. For holding the assembly there is a handle 4 opposite the chuck key, which bevel-geared chuck key has a constant diameter over its length 7 with two wings 8 at the end for correctly holding the bevel-geared key. <IMAGE>
