L'invention concerne un dispositif de blocage en rotation (110) destiné à empêcher un écrou (103) d'un arbre rotatif (101) de tourner. L'écrou (103) comporte un filet pourvu de flancs montant dans une première direction de pas. Un premier angle formé entre une direction d'étendue axiale de l'écrou (103) et la première direction de pas présente un premier signe. Le dispositif de blocage en rotation (110) est caractérisé en ce que le dispositif de blocage en rotation (110) comporte une bague de blocage (104) pouvant être vissée autour de l'arbre (101) de façon coaxiale par rapport à l'écrou (103) et comportant un filet pourvu de flancs montant dans une deuxième direction de pas. Un deuxième angle formé entre une première direction d'étendue axiale de la bague de blocage (104) et la deuxième direction de pas présente un deuxième signe.
