Abstract
The clamping system is used for connecting two pipes whose facing ends have protruding bearing surfaces. The clamping system comprises a collar that can be clamped and a washer. The collar includes a belt whose internal periphery delimits a recess into which the bearing surfaces can be inserted. The washer comprises an annular part disposed inside the belt and carrying support lugs which have a hook configured to hook on an edge of the belt and a link section which extends between the annular part and the hook. The link section carries at least one retaining wing bent radially outwardly and having a retaining edge, the retaining wing having a width, measured axially, which decreases towards its free end, the edge of the belt being housed in the space formed between the retaining edge and the hook.
