Abstract
System of coupling of the head of a drive unit to the body of a driven unit, characterized in that, the head bears a longitudinal key having two slopes inclined in relation to the axis of the head, and the body has a guiding or key-way groove for this key, this groove opening on an annular clearing in which a segment can be rotated against a spring and in which a pin is fastened radially, so that, while the key is engaged, this pin, by cooperation with the first of the slopes controls the rotation of the segment, then by cooperation with the second slope controls the blocking of the head in its driving position, and the segment can also be operated by hand so as to free the pin and allow the withdrawal of the head by drawing the key rearwardly.
