A rod with a tubular, fibre-composite wall, cut into two parts has actively controllable, pressure- and tension-generating elements which are effective in an axial direction of the rod, provided therebetween. An exterior pressure-generating element, which effects an elongation, takes the form of a cylindrical ring and is disposed on the outside of the rod elements. For the cylindrical ring, stop shoulders are formed on the outside of each of the rod elements. A second force-generating element is disposed inside the rod. Disposed in each of the two rod elements are loops or bends which are axially fixed to the rod elements and are guided around the axially opposite ends of the second force-generating element so that they in each case overlap or extend around the end of the second element which is directed axially away from the rod element in which the loops are fixed. Upon elongation of the second element, tensile forces are exerted upon the two rod elements and draw said two rod elements together.
