A connection, having an anchored, elongated tension member, a fastening member attached to the tension member, a resisting member receiving the tension member and an expansion device receiving the tension member there through and compressively loaded between the fastening member and the resisting member by the fastening member on the tension member. First and second bearing members are received in a central aperture of a surrounding sleeve and operatively connected thereto. At least one of the bearing members is threadably connected to the sleeve, and rotatable in relation thereto. A torsion spring connects the first and second bearing members and is located within the surrounding sleeve. The torsion spring biases the first and second members in opposite rotational directions with at least one of the bearing members forced to rotate along the thread out of the surrounding sleeve away from the other bearing member.
L'invention concerne une connexion, comprenant un câble de tension oblong ancré, une pièce de fixation attachée au câble de tension, une pièce résistante qui reçoit le câble de tension et un dispositif d'expansion recevant le câble de tension et chargé compressivement entre la pièce de fixation et la pièce résistante par la pièce de fixation sur le câble de tension. Une première et une deuxième pièces d'appui sont reçues dans une ouverture centrale d'un manchon avoisinant auquel ils sont connectés de manière efficace. Au moins une des pièces d'appui est liée par enfilage au manchon autour duquel il tourne. Un ressort de torsion, situé dans le manchon avoisinant, relie la première et la deuxième pièce d'appui. Le ressort de torsion polarise la première et la deuxième pièces dans des directions rotatives opposées, ce qui force au moins une des pièces d'appui à tourner autour du filetage du manchon avoisinant, à distance de l'autre pièce d'appui.
