Abstract

Une aube comprenant un corps principal (1) auquel est assemblé un couvercle (2) de fermeture d'une cavité intérieure (3) est assemblée par l'imbrication de saillies (5) du couvercle (2) dans des feuillures (6) de l'ouverture de la cavité. Dans l'invention, les saillies (5) sont au bout de pattes (8) indépendantes les unes des autres, de sorte qu'on peut les fléchir chacune de la valeur voulue, ce qui peut faciliter l'assemblage d'aubes de forme irrégulière et notamment à forte courbure.
