Abstract

Un appareil pour agripper un câble comprend un boîtier (42) et un moyen récepteur (52, 53, 54, 55) pour recevoir un élément plan (11) pour agripper un câble. L'élément plan se présente sous la forme d'une plaque métallique ayant une pluralité de creux (16a, b) formés dans une surface de bord latérale (15), le creux (16a, b) ayant les portions internes de paroi latérale (24) séparées par une distance (32) qui leur permet de comprimer une portion périphérique d'un câble placée de manière à être forcée entre celles-ci et se voir appliquer de ce fait une force de rétention s'opposant à une force axiale appliquée à une extrémité du câble. Le boîtier (42) a une portion supérieure et une portion inférieure qui sont agencées pour être connectées ensemble et former un logement avec une entrée (44, 45), l'élément plan étant agencé pour être tenu à l'intérieur du logement par le moyen récepteur (52, 53, 54, 55).
