The rim element (1) is open on the outside part where it has bent-over lugs (6, 7) each having a hole (12). The sides (4) have one end in the form of a fork with two teeth (8, 9) equipped with pivot pins (10, 11) engaged in the holes (12) of the lugs (6, 7) of the rim element and ensuring the articulation of the sides of the frame. Fitting lenses into the rim element (1) is thus simplified. <IMAGE> |
