A manipulator comprising a linkage with at least two links ( ) which have ball joints ( ) at their ends, and a spring device ( ) which exerts a tensile force between the links. The spring device ( ) comprises a first drawing device ( ) with a first angle device ( ), a second drawing device ( ) with a second angle device ( ), which are arranged, displaceable in parallel, side-by-side, and a spring member ( ) arranged between the angle devices. The tensile force arises by the spring member exerting a compressive force against the angle devices.
