Abstract: A rod with a tubular wall made from carbon fibre composite material and having connecting elements arranged at both ends. The tubular wall is divided in the center of the rod and an actively controllable pressure element, which acts in the axial direction of the rod, is built into the rod and lies against the inner faces of thrust washers, whilst the end faces of the divided tubular wall rest against the outer faces of the washers. Over the region of the element on the outer face of the tubular wall there is disposed a sleeve which engages over and is glued to the adjacent ends of the rod.
