A holdback prevents the rotation of a shaft in the other direction, and has a teething in a housing wall (16a), through which the shaft passes. The lateral surface of the shaft has many recesses in the area of the housing wall and a ring is arranged in the same area, which has multiple outward projecting hooks and inward projecting counter hooks. The hooks project in the teething of the housing wall and the counter hooks project in the recesses of the lateral surface.
