La présente invention concerne un système permettant d'empêcher le déplacement d'un élément de serrage, le système comprenant un élément de serrage en association mobile avec un premier élément, et au moins un élément de verrouillage associé de manière mobile audit premier élément et audit élément de serrage. Lorsque ledit élément de serrage est déplacé vers l'axe longitudinal dudit premier élément, ledit au moins un élément de verrouillage est mobile vers l'élément de serrage afin d'empêcher ledit élément de serrage de s'éloigner dudit axe longitudinal jusqu'à sa position initiale.
