Abstract
A fastener having a grip member ( ) that is insertable into a mounting space ( ) of a hollow structure ( ) and serves in the detachable fastening of an object to the hollow structure. The grip member ( ) is rotatable inside the hollow structure such that the grip member ( ) grips behind holding projections provided inwardly of the hollow body longitudinal walls. The holding projections are for fastening of the object between a stop ( ), that outwardly abuts the edges of the hollow structure's longitudinal walls ( ) lining the mounting space and can be fixedly clamped to the grip member ( ). A spring biased element ( ) acting perpendicular to the stop ( ) is arranged between the grip member and the stop. The result is that pre-fixation of the fastener to the hollow structure is made possible. By means of a coupling ( ) between the stop ( ) and the rear grip member ( ) its positions are precisely fixed.
