Abstract
The clamping device comprises 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 this stress to allow the insertion of an annular object between the seal and the belt.
Claims17
A clamping device comprising a collar which has a belt able to adopt an unclamped state and a clamped state in which a diameter of the belt is reduced compared to the unclamped state, and a seal disposed inside the belt by being retained axially relative to the collar, the seal being formed in a strip, which is wound on itself and whose ends are configured to cooperate together via a sealing arrangement, wherein, in the unclamped state of the belt, the pre-mounted seal disposed inside the belt undergoes a stress towards an inner surface of the belt, the seal being configured to be elastically deformed against this stress to allow the insertion of an annular object between the seal and the belt.
A tube clamping assembly, comprising a clamping device and a tube, the clamping device comprising a collar which has a belt able to adopt an unclamped state and a clamped state in which a diameter of the belt is reduced compared to the clamped state, and a seal disposed inside the belt by being retained axially relative to the collar, the seal being formed in a strip, which is wound on itself and whose ends are configured to cooperate together via a sealing arrangement, wherein, in the unclamped state of the belt, the pre-mounted seal disposed inside the belt undergoes a stress towards an inner surface of the belt, the seal being configured to be elastically deformed against this stress to allow the insertion of an end of the tube between the seal and the belt.
