Abstract

L'invention concerne un élément (10) d'identification pour compteur d'eau. Le compteur d'eau possède un boîtier de compteur muni d'un oculaire et d'une bague (1) à visser pour fixer un mécanisme de mesure et l'oculaire (3) sur le boîtier du compteur. L'oculaire (3) comporte sur son côté extérieur une came (4) de butée. L'élément (10) d'identification comprend une surface partiellement annulaire avec un côté (11) supérieur et un côté (11') inférieur, au moins une baguette (13) dont la section transversale est approximativement en forme de L adaptée au côté intérieur de la bague à visser et qui est façonnée sur le côté (11') inférieur, et une languette (14) élastique sur la baguette (13). En position montée, la languette (14) s'enclenche derrière la came (4) de butée.
