Arrangement in connection with clamping tools

An arrangement in connection with clamping tools, which comprises a nozzle structure which consists of coaxially arranged nozzle elements (1, 2) and is arranged to form one or more layers which cover a flexible elongated element (3) on the surface of the flexible elongated element, which passes through the innermost nozzle element (1), in which arrangement at least the head of the nozzle element (1), which controls the flexible elongated element, is a separate unit (4a, 4b, 4c), which is arranged to be pushed into its position in the direction of the flexible elongated element (3) and provided with gripping means (5), which grip the innermost nozzle element (1) of the nozzle structure as the unit (4a, 4b, 4c) arrives at the nozzle element (1), characterized in that the joint between the separate unit (4a, 4b, 4c) and the nozzle element (1) of the nozzle structure is arranged to be loosened by repulsive force acting on the separate unit in the direction of the flexible elongated element (3) and that the separate unit (4a, 4b, 4c) is arranged to exit from the nozzle structure in the direction of the flexible elongated element (3).
