Abstract
The clamping system is used to connect a first and a second tube whose facing ends have bearing surfaces protruding relative to their cylindrical external surface. The clamping system has a clampable collar and a seal. The collar includes a belt able to cooperate with the bearing surfaces of the tubes by this internal periphery delimiting a recess into which the bearing surfaces can be inserted. The seal is supported by the collar in the unclamped state of the latter and includes an annular sealing portion which includes a first washer and a second washer fixed to the first washer by retaining lugs carried by the first washer.
