The invention relates to an auricular label including a fastening system that combines, with a male part, a female part comprising a button having an opening and a cavity for receiving the male portion, said button including an essentially cylindrical or frusto-conical head and a circular surface extending in a plane substantially perpendicular to the axis of the head from the base thereof, said loop being characterised in that the surface of the reception button includes at least two perforations ensuring the communication of the lower face of the surface with the atmosphere. The label of the invention ensures an improved healing of the insertion point into the ear of the animal, without impairing the rigidity or the solidity of the button, and without permitting the forced extraction of the male part or any other manipulation for forging the data contained in the ring.
