Abstract

The connection is made by the engagement of profiled parts (11, 12) of the end piece (1) of the arm of the machine between one face (26) of the tool and corresponding profiled parts (20, 21) of the tool. The profiled parts have ramps and are kept engaged by a locking means exerting a transverse pressure in such a way that the play is taken up automatically. The connection is compact and advantageous in mechanical terms. <IMAGE>
