Abstract

La présente invention aborde le problème de la réalisation d'un manchon qui peut être installé en un temps court et qui présente une exceptionnelle aptitude au façonnage. La solution selon l'invention porte sur des capuchons (200) qui sont fixés à un moule (24), et des parties saillantes (222) formées sur les surfaces circonférentielles (220) des capuchons (200) sont ajustées dans des ouvertures (124, 164) formées sur le côté d'ouverture d'un corps de manchon (100). Le corps de manchon (100) peut être fixé aux capuchons (200) en une seule action, et le travail de fixation d'un manchon (10) au moule (24) peut être réalisé en un temps court. Après que le moule (24) a été retiré, les parties saillantes (222) des capuchons (200) sortent par une simple extraction de bagues d'extraction (226) des capuchons (200), et les capuchons (200) peuvent être retirés facilement.
