Abstract

L'invention porte sur une attache de traction pour une liaison libérable à une extrémité de train de tiges de sommet de trou émoussée d'un train de tiges continues. Un corps d'attache principal a un trou d'attache à travers celui-ci, et a une ouverture de réception de train de tiges à l'extrémité de traction pour recevoir l'extrémité de train de tiges, et un trou d'actionnement à l'extrémité tirée et un trou effilé entre celles-ci. Un insert effilé ayant un trou de saisie radialement compressible peut être enfoncé dans le trou effilé et peut être actionné axialement entre une première position de réception passive, pour recevoir l'extrémité de train de tiges, et une seconde position de saisie active pour comprimer radialement l'insert effilé autour de l'extrémité de train de tiges pour saisir activement l'extrémité de train de tiges à l'intérieur de celui-ci. L'insert effilé peut être actionné axialement à l'aide d'un corps principal fileté et d'un capuchon supérieur fileté pour prendre en sandwich l'insert effilé entre ceux-ci, le capuchon supérieur étant fileté axialement à l'intérieur et à l'extérieur de l'extrémité tirée du corps principal entre les positions passive et active.
