Abstract: The invention concerns an eyelet (O) of the type constituted by two half-shells (100 and 200) assembled by clipsage used as border and/or reinforcement of perforations in curtains, textiles or similar materials, the two half-shells (100 and 200) coming mutually into grasp by clipsage, one of the two half-shells (100 and 200) having a plurality of fins (120) projecting from its face turned towards the interior of the other half-shell (200) and the points (121) of which are introduced into the circular annular groove (220) laid out for this purpose in the interior surface of the other half-shell (200). This eyelet is notably characterized in that the aforementioned fins (120) have a body adopting a polygonal cross-section.
