Abstract: An arrangement for a fixation, which is applied to a ladder is provided. The ladder includes at least one hollow rung. A bolt is located longitudinally and inside the hollow rung. The bolt includes at its first side an eye, which is used as attachment-point for attachment-purposes, while the eye is located outside the hollow rung on a first side of the ladder. The bolt includes at its second side an interlock, which can be engaged at a second side of the ladder firmly but detachably, so a movable attachment-point is originated at the ladder by the hollow-rung, by the inserted bolt and by the eye and the interlock, which are connected with the bolt.
