The invention relates to an ear tag (1) for identifying animals, enabling a sample of biological tissue to be taken when the tag is applied to the animal. Said tag comprises a male part (2) and a female part (3) which are assembled by irreversible socketing. The stem of the male part comprises a detachable head (23) having a hollow distal part provided with a cutting edge (25) for cutting out a biological sample when the head perforates the ear of the animal. The female part comprises a central tube (31) for receiving the head and at least partially receiving the stem when the ear tag is applied, said tube being associated with a detachable sample container (32) arranged in the axial extension of the tube. The proximal end (35) of the container has a first opening (33) for receiving the head (23) of the stem when the ear tag is applied, and the distal end (36) of the container has a second opening (34) enabling the inside of the sample container to be reached. The invention also relates to a device comprising a sample container (32) associated with the hollow head (23) containing the sample obtained when the identifying ear tag is applied to the animal, and a protection tube comprising a closing cover. Said device enables the sample taken to be stored in a closed space and analysed later. The sampling system is designed in such a way as to enable the sample to be easily handled and accessed for the analysis thereof.

L'invention a pour objet une boucle auriculaire (1 ) pour l'identification des animaux, permettant le prélèvement d'un échantillon de tissus biologiques au moment de l'application sur l'animal, comprenant une partie mâle (2) et une partie femelle (3) assemblées par emboîtement irréversible, - la tige de la partie mâle possédant une tête (23) amovible dont la partie distale (27) est creuse et est dotée d'une arête tranchante (25) apte à sectionner un échantillon de matière biologique lorsque ladite tête perfore l'oreille de l'animal, - et la partie femelle comportant un conduit central (31 ) apte à recevoir ladite tête et au moins partiellement ladite tige lors de la pose de la boucle d'oreille, ledit conduit étant associé à un conteneur d'échantillon (32) détachable placé dans le prolongement axial dudit conduit, ledit conteneur ayant à son extrémité proximale (35) une première ouverture (33) apte à recevoir la tête (23) de ladite tige lors de la pose de la boucle d'oreille, et comportant à son extrémité distale (36) une seconde ouverture (34) donnant accès à l'espace intérieur dudit conteneur d'échantillon. Un autre objet de la présente invention concerne un dispositif comprenant un conteneur d'échantillon (32) associé avec la tête creuse (23) contenant l'échantillon obtenu lors de la pose de la boucle d'identification sur l'animal, et un tube de protection doté d'un couvercle de fermeture. Ce dispositif permet de conserver l'échantillon prélevé dans un espace clos et de l'analyser ultérieurement. Le système de prélèvement est conçu de sorte que l'échantillon soit facilement manipulable et accessible pour son analyse.
