Abstract
A clamping device including a collar which has a belt able to be clamped by the reduction of its diameter and a seal disposed inside the belt by being retained axially relative to the collar. The seal is formed in a strip which is wound on itself and whose ends are configured to cooperate together via a sealing arrangement. The seal undergoes a stress towards the inner surface of the belt and is configured to be elastically deformed against the stress to allow the insertion of an annular object between the seal and the belt.
