The ring is composed of a closed rigid material hub (2) in the shape of a circular gutter. A decorative section (3) is inserted like a tire in the hub gutter. The two ends (3b,3c) of the decorative section face each other in the gutter. An elastically deformable joint cover (4) comprises a split ring transversely surrounding the core formed by the hub and decorative section in the junction zone of the section ends.
