摘要

The eyeglasses (1) have two lateral branches (3), where each branch comprises a tenon (4). An articulation (5) is interposed between the branch and the tenon. A fastening unit detachably connects the branch on the tenon. The articulation is arranged transversely to a longitudinal axis at an end to revolve in a bearing formed in the tenon, to form a lock (9) engaged on the tenon in a withdrawal position and to allow the engagement of the tenon in the bearing and sliding of the bolt close to the bearing on the axis to obtain a screwless articulation with the interchangeable branch.
