The antiskid tyre chain has a fastener with a securing element (7) which comprises a securing fork (12) which is mounted on the hook part (9) of the hook-shaped fastening member (4) near to the hook lug (11) such that it can pivot around a rotational axis (13) arranged transversely with respect to the plane of the fitting clip (2). The securing fork (12) has a fork leg (14) which rises up at a distance behind the hook part (9) and has a sliding surface (15) which guides the eye-shaped mating fastening member (5) into a hooked-in position behind the hook part (9). In addition, the securing fork (12) has a securing lug (17) which is bent back approximately in the shape of an L from the other fork leg (16) and which, after the eye-shaped mating fastening member (5) has been inserted into the insertion opening (6) on the securing fork (12), engages in a locking manner over the eye web (19), hooked into the hook part (9), of the mating fastening member (5) on the hook part (9) and is secured in the fastening position. The securing fork (12) is moreover designed in the manner of a rocker and has a locking lug (31) which, in the fastening position, engages in a locking manner into the elongate eye opening (32) of the mating fastening member (5) and secures the mating fastening member (5) on the hook-shaped fastening member (4) against being displaced or shifted in the circumferential direction of the fitting clip (2). In order to open the fastener (3) the chain section (41), connected to the mating fastening member (5), of the running net is pulled and thus the eye-shaped ... Original abstract incomplete.
