This is an advantage, especially in confined installation situations. Instead of having to provide the entire length of the locking bar next to the shackle device, only the diameter of the locking bar below the shackle device (ie relative to the shackle eyes) must be present. In addition, no thread must be screwed for safe use, which leads to a simplification and acceleration of the closing process.

Abstract

La présente invention concerne une manille permettant de relier deux objets. Ladite manille comporte une tige de fermeture (120) présentant une direction longitudinale (125), et un corps de fermeture (110). Le corps de fermeture comporte un étrier (111) et deux oeillets (112 ; 113), lesdits oeillets (112 ; 113) formant chacun un évidement récepteur pour la tige de fermeture (120), dans lequel la tige de fermeture (120) peut être introduite dans la direction radiale de l'oeillet (112 ; 113). L'introduction de la tige de fermeture (120) dans les oeillets (112 ; 113) permet à ladite tige (120) de fermer l'étrier (111) du corps de fermeture (110), et le pivotement de la tige de fermeture (120) verrouille la manille (100).
