Abstract

Dispositif de fixation fileté (12) qui s'auto-verrouille en étant serré sur un objet (14) qui y est fixé. Le filetage (30) comprend une ou plusieurs parties (48) qui sont décalées, ce qui produit une ou plusieurs discontinuités. Chaque partie décalée (48) du filetage (30) est entièrement formée au niveau de la discontinuité. Les parties décalées (48) vont déformer un filetage intérieur relativement plus mou, ce qui amène le filetage déformé à se déplacer au-dessus des faces terminales (56) des parties décalées (48) et à s'entasser à l'avant des faces terminales (56) afin d'éviter tout relâchement significatif du raccord.
