The present invention pertains to a safety system for steering shafts, in which shaft parts non-rotatably engage each other and are secured against relative displacement in relation to one another by injected shear materials, which are designed for maximum axial forces in the steering shaft and engage recesses on the outer circumference of the inner shaft part and on the inner circumference of the outer shaft part. Such a safety system has an at least double telescoping shaft system, in which at least two shaft parts are connected to one another by an intermediate shaft part, and the inner shaft parts engage a radial expansion of the corresponding outer shaft part, and a cross section of the shear material designed for shearing is arranged between the shaft parts in the area of the expansion.
