The inventive device is of the type which consists of an information medium comprising at least one non-circular through hole and support means for said information medium, comprising a ring (3) which is provided with an external rod (4). Moreover, the free end of said rod is equipped with a head (5) that is intended to be inserted in the aforementioned hole. The invention is characterised in that the head (5) of the support means and the hole in the information medium are shaped such that, in a first relative angular position between the information medium and the support means, the information medium can be mounted on the rod (4) by passing the head (5) through the hole and, in a second relative angular position, the information medium can be held in place on the rod (4) by means of the head (5). |
