Abstract

L'invention concerne une fermeture rapide dotée d'un tourillon et d'une pièce élastique. Le tourillon comprend une tête de tourillon et une tige de tourillon, la pièce élastique présentant au moins deux branches élastiques qui s'étendent dans le sens de la longueur de la tige de tourillon et étant reçue en position centrée sur le tourillon. Le tourillon peut tourner autour de son axe longitudinal dans la pièce élastique et la tige du tourillon présente des éléments plats qui, lors de la rotation du tourillon, ont pour effet dans une position angulaire définie un évasement des branches du ressort en opposition à la force des branches du ressort. L'invention prévoit de configurer la pièce élastique (20) et le tourillon (10) de telle sorte que le tourillon (10) puisse être enfiché par un déplacement exclusivement de translation dans la pièce élastique (20) jusqu'à ce que la tête du tourillon (10a) vienne se placer sur la pièce élastique (20) et y soit immobilisée en correspondance géométrique dans la direction de son axe longitudinal, dans une position d'encliquetage dans la pièce élastique (20) détendue.
