ABSTRACT:
Tool mounting is effected by engagement of profiled parts of the end piece of the machine jib between a face of the tool and corresponding profiled parts of the tool. The profiled parts have ramps that are maintained in engagement by a locking mechanism exerting a transverse pressure so that the play is automatically taken up. The mounting is compact and favorable from a mechanical point of view in that the ramps, not the locking mechanism, carry the working load.
