L'invention porte sur un mécanisme de raccord pour un dispositif de prévention de glissement d'un pneu, le mécanisme étant conçu pour relier l'une à l'autre les extrémités de raccord d'un corps de prévention de glissement de pneu dans la direction périphérique du pneu, le raccord n'étant pas déconnecté même si un fil se desserre, l'épaisseur du mécanisme étant réduite autant que possible de façon à ce que le mécanisme soit adaptable d'une manière plus appropriée à un véhicule, le mécanisme facilitant la fixation et le détachement l'une de l'autre des extrémités du raccord. La configuration dudit mécanisme comporte : une extrémité d'insertion qui présente une tête de raccord, reliée à une extrémité d'une extrémité de raccord, ainsi qu'une section tige, disposée à un point adjacent à la tête de raccord et dont le diamètre est inférieur au diamètre de la tête de raccord; et un élément de raccord relié à l'autre extrémité de l'extrémité de raccord, l'élément de raccord étant muni d'un moyen de fixation/détachement pour fixer et détacher l'élément de raccord de l'extrémité d'insertion. Dans la surface de pointe de l'élément de raccord, il est ménagé un trou d'insertion dont le diamètre permet d'insérer la tête de raccord dans le trou d'insertion, et une section découpée formée sur un côté du trou d'insertion et dont la largeur est telle qu'il est difficile d'insérer la tête de raccord, mais il est possible d'insérer la section tige. Le moyen de fixation/détachement possède un mécanisme de verrouillage capable de maintenir un état dans lequel l'extrémité d'insertion a été déplacée dans la section découpée, et le moyen de fixation/détachement possède un mécanisme de déverrouillage permettant une libération manuelle de l'état verrouillé assuré par le mécanisme de verrouillage.
