In addition device has central axial control member and external shielding housing. In addition device has clamping pulley, clamping head, clutch which connects pulley with cable core and jacket which is mounted for connection to outer shielding housing of cable. In addition device has flexible tube with grooves for ribbons of cable, which are designed for coaxial position with respect to grooves of cable core. In addition device has deflecting tube which is mounted over pulley and has longitudinal sockets for mounting optical connectors. In addition device has two units for preliminary load of device members along pulley. First of them is located between flexible and deflected tubes, second one is located between deflected tube and clamping head. Flexible tube is located over pulley for connection to clutch in order to prevent rotation of flexible tube around clutch. Jacket is designed as series of tube pieces which are connected to one another by hinges and are mounted over flexible deflected tube. EFFECT: increased functional capabilities. 22 cl, 10 dwg
