Abstract

Une douille ou un élément analogue selon l'invention se compose d'un certain nombre de segments de serrage 2 qui sont chacun séparés d'un segment ou mors 2 adjacent par un séparateur élastique 12 en forme de plaque qui est maintenu en place entre les deux mors. Les faces opposées du séparateur 12 sont en contact avec des faces latérales, orientées radialement, des mors 2 et sont nervurées en forme de grille pour augmenter l'élasticité des séparateurs et diminuer l'effort de fermeture (de compression) de la douille sur la pièce. Grâce aux séparateurs 12, une même douille permet dé serrer des pièces d'une gamme de diamètres, tout en maintenant un serrage parallèle.
