The device has two supports (15, 16) which can be moved in relation to each other in a transverse direction to the axis (2) of the traction element (1). Several clamping jaws (19, 20) are displaceably mounted in pairs opposite each other on said supports. The clamping jaws (19, 20) have surfaces which grasp the traction element (1). When strain is placed on the traction element, the clamping jaws are displaced linearly at increasing distances except for the rear pair, in such a way that the clamping force can be evenly distributed over a great length, despite the extension of the traction element (1). This allows, for example, steel cables with a high traction force to be tensioned without damaging the cable. |
