A device (10, 110) for preventing an incorrect filling of a tank of, e.g., motor vehicles by a gas hose nozzle (215, 315), is provided with a permanent magnet array (11, 111, 211, 311), which has a partial array (213, 313) preferably in the form of a single magnet in the discharge pipe (216, 316) of the gas hose nozzle (215, 315), and has another permanent magnet partial array (12, 112), including a plurality of permanent magnetic elements (24, 124) arranged in a ring-shaped pattern. The permanent magnets (24, 124) are held in a closed or open body (23, 123, 223), the body (23, 123, 223) has a closed or open ring-shaped design, and the north and south poles, of the permanent magnetic elements (24, 124), are aligned in the radial direction or in the direction of a longitudinal axis of the filler neck (20, 120). |
