This invention relates to a length adjustment device for adjusting predetermined maximum or minimum playless distance between two points (A) and (B). Known devices of this kind require visual inspection during the adjustment. The invention avoids the necessity of visual inspection by arranging a protruding means (52) at the end surface of the adjustment screw (5). This protruding device (52) interacts with a slot (23) in one of the longish elements (2,3), which are pivotally cojoined and form the actual length adjustment device (1).
