Abstract: Clamping system for connecting two tubes having protruding clamping surfaces. The system comprises a collar having a strip able to cooperate with the clamping surfaces. The strip has a first and a second flank between which an inner recess able to receive the clamping surfaces is delimited. The system has at least one retaining clip having a cross-member which extends across the inner recess, a first and a second wing which extend radially outwardly relative to the cross-member by covering the flanks and a first and a second retaining configuration each having at least one retaining lug. The cross-member is able to be deformed to penetrate into the inner recess.

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.
