The invention relates to a fixing assembly for attaching supplemental lenses, binocular loupes and the like to spectacles. The fixing assembly comprises a clip (6) which is tightenable by means of a screw (7) into the engagement with a bridge (3) connecting the rims of actual lenses across the nose. The clip (6) comprises a clamping hook (10) constituting a loop which grips around said bridge (3) and whose ends are received in a hole (11a, 11b) extending through a clip body (8, 9; 6b) and dimensioned relative to the screw (7) such that threads of the screw (7) engage with the clamping hook (10). Attachments (4; 18) are secured by way of thin arms (5; 20-26) to said clip (6) to which a yoke-like holder can also be fastened by means of a snap fit.

La présente invention concerne un assemblage de fixation de lentilles additionnelles, de loupes binoculaires et autres sur une paire de lunettes. Il comprend une bride de serrage (6) qui peut être serrée par une vis (7) pour qu'elle soit solidaire d'une barre (3) reliant les cercles des lentilles proprement dites de part et d'autre du nez. La bride de serrage (6) comprend un crampon de fixation (10) qui forme une boucle passant autour de la barre (3) en la serrant et dont les extrémités sont logées dans un trou (11a, 11b) qui passe dans un corps de bride (8, 9; 6b) et dimensionné, par rapport à la vis (7), de telle façon que des filets de la vis (7) s'engrènent avec le crampon de fixation (10). Des accessoires (4, 18) sont fixés, au moyen de tiges minces (5; 20 à 26), à la bride de serrage (6), à laquelle un support en forme de joug peut aussi être fixé par une fixation instantanée.
