A linear element, especially a spectacle side, of the type comprising a flexible metal core coated with a flexible elastomer for comfort and/or appearance. Its structure is composed of a plurality of rigid plastic rings placed in fixed positions around predetermined areas of the flexible metal core so that each can serve as a point of intermediate mechanical attachment of the flexible elastomer with respect to the core. The cross section of the rings are inscribed within that of the elastomer surrounding it. |
