Abstract

L'invention concerne un élément de fixation pour fixer au moins deux corps non alignés l'un à l'autre comprenant un récepteur d'élément de fixation, un élément de fixation conforme au trajet et un canal de guidage. Le récepteur d'élément de fixation est configuré pour fixer un premier corps non aligné, et l'élément de fixation conforme au trajet est configuré pour fixer au moins un second corps non aligné. L'élément de fixation conforme au trajet traverse le canal de guidage et vient en prise par filetage avec le récepteur d'élément de fixation, le canal de guidage pouvant être une ouverture à travers le second corps non aligné ou un adaptateur séparé qui est inséré ou incorporé dans le second corps non aligné. La fixation entre les deux éléments de fixation à verrouillage mutuel est achevée avec une première section de fixation du récepteur d'élément de fixation et une seconde section de fixation de l'élément de fixation conforme au trajet autour d'un bord inférieur du guide de canal entre des sections de siège de couplage à verrouillage mutuel de corps non alignés supplémentaires sur toute la longueur du canal de guidage, fixant ainsi les deux (ou plus) corps non alignés.
