<p>The ring (5) has two internal and external concentric and annular portions (5a, 5b) e.g. crowns, which are linked by radial arms (7), where the portions are continuous or non-continuous and are plane and parallel to each other. One of the portions (5b) has a large diameter and comprises a plane part, and the other portion (5a) is configured as a snap ring or a circlip. The radial arms form an angle (teta) with respect to a plane of the plane part. The portion (5b) has pierced extensions extending in an opening, and is separated into annular sectors, where each sector has curved extremities.</p> |
