A protective casing with ring for shafts, in particular cardanic shafts. It comprises, coaxially, a casing, a sleeve ring, and a tubular element. A first end of the sleeve of the ring is destined to engage with a circumferentially groove of the joint, and a second end of the sleeve is adjacent to a constraining end of the casing encompassing the ring. The ring and the casing present, in their respective constraining ends, a multiplicity of hook shaped circumferentially equidistant protrusions, destined to be juxtaposed alternatively forming a circumferential throat for a split elastic locking ring. A rigid annular safety element may cover said constraining ends of the casing and of the ring. |
