Abstract: A compression ring made of an initially open clamping band has ends which mutually engage in puzzle-like fashion for closing the compression ring. One band end carries a tongue which projects in the longitudinal direction of the band and has arms extending transversely to the longitudinal direction of the band, and the other end of the band is formed complementarily thereto. The transverse edges of the arms, which extend transversely to the longitudinal direction of the band and face the free end of the tongue, each have a convex part at the outer end and a concave part at the inner end.
