<p>A device for fixing the hub of an arm of a wind-screen wiper (2) on a pivoting axis (1) with locking elements (6, 7) for the arm on the pivoting axis (1), a cavity (32) which is created in the hub (2) and is provided with adjusting and angular positioning elements for the arm in relation to the axis (1), whereby the hub (2) rests on the base of a stop (3) which nestles on a radius of operation (4) of the said axis (1); the locking elements (6, 7) are adapted in such a way that they can be engaged in a locking or unlocking position, the adjusting elements includes a connecting ring (10) which is rotationally fixed to the axis (1) and accommodated in the cavity (32) of the hub (2) with a certain amount of play allowing for limited relative angular displacement between the connecting ring (10) and the hub (2) when the locking elements (6, 7) are in an unlocked position, whereby all relative displacement is prohibited between the connecting ring (10) and the hub (2) when the locking elements (6, 7) are in a locked position.</p> |
