Abstract

L’invention concerne un assemblage comprenant des vis (300) de fixation, des brides (26,25), des premiers écrous (39) dans chacun desquels sont vissés les vis, des seconds écrous (53) vissés axialement et respectivement autour desdites vis, et des clés de verrouillage (35,350) s’opposant au dévissage des seconds écrous. Les vis (300) viennent serrer axialement les clés de verrouillage entre des têtes élargies (305) de ces vis et les premiers écrous (39). Radialement, les seconds écrous (53) sont disposés à l’intérieur des clés de verrouillage, lesquelles s’opposent à la rotation des vis (300), par coopération de formes venant en contact.
