ABSTRACT:
A clamp for clamping a hose fast on a pipe clamp that includes a clamp band and a spring ring that is fixed with a first portion thereof to the clamp band. The spring ring elastically clamps the hose when the clamp is initially fitted on the hose, but is not yet clamped fast to the hose At least a second portion of the spring ring is at least predominantly disposed within the clamp band. The spring ring is made of spring steel sheet so that the clamp can be made compact to save material. The spring ring provides a firmer locking of the initially fitted clamp on the hose and ensures that the clamping force of the clamp is more uniformly distributed over the periphery of the hose because the clamp can slide on the outer circumferential surface of the spring ring.
