L'aiguille comprend en outre un élément de liaison (8) qui vient en prise autour de l'élément de transmission (11) ou de l'élément languette au moins le long d'une partie de la longueur de l'organe de transmission (11) ou de l'élément languette, de sorte que le déplacement relatif de l'organe de transmission (11) ou de l'élément languette par rapport au corps de base (1) soit guidé par l'élément de liaison (8), l'élément de liaison (8) étant relié à une partie supérieure du corps de base (1).
