The protective ring (7) consists of flexible material. Its diameter (2) is chosen so that it can be drawn over a finger to engage over the ring and on the skin. The elastic ring is wider than the finger ring, and is formed as a hollow cylinder with a C or U-shaped profile. The outer ring edges (5) are rounded. The protective ring may consist of an outer and an inner ring body. It is of foam or plastic, and has an outer washable surface (6), which may carry imprints.
