Abstract

L'invention concerne un élément (13) pour une paire de lunettes prévu pour être associé à un verre (11). Cet élément se caractérise en ce qu'il comprend, sur une zone d'extrémité, une première partie plate (34) et une deuxième partie plate (35) qui sont mutuellement perpendiculaires. Un trou transversal (38) est ménagé dans la deuxième partie (35). Les première et deuxième parties (34, 35) de l'élément sont prévues pour reposer respectivement contre le bord et la partie adjacente de l'un des côtés du verre (11), de telle sorte que le trou transversal (38) ménagé dans la deuxième partie (35) est aligné par rapport au trou traversant correspondant (37) ménagé dans le verre en vue de l'insertion d'une vis de blocage (41) dans ce dernier. Au moins une des première et deuxième parties est pourvue d'un élément en saillie (39) qui est couplé de manière rigide à ces dernières et peut interférer avec le verre (11) pour éviter tout mouvement de rotation indésirable de ce dernier.
