<p>A first unit (1) of the ear tag comprises a first button shaped element (3) and first connecting means (4) extending from said first element (3). A second unit (2) of the ear tag comprises a second button shaped element (5) and second connecting means (6) provided with a cavity (7) behind an opening (15) for receiving the far end (8) of the first connecting means (4), The first connecting means (4) are adapted for perforating an ear (9) and for subsequent plastic deformation inside the cavity (7). Compared with conventional ear tags, a reduced frequency of ear injuiries can be achieved and fraudulous exchanging of ear tags can be counteracted. The disclosed ear tag can be produced at low cost and can easily be fixed to the ear. A device for attaching the disclosed ear tag to an ear is also described. <IMAGE></p> |
