Abstract

The inventions relates to a screw-nut assembly having an integrated immediately effective safeguarding against an unintentional loosening of a screw connection formed therewith. Said screw-nut assembly comprises a first screw connection body and an associated second screw connection body. The invention is characterized in that one of the two screw connection bodies (1) has a free-wheel (3) that is connected thereto in a rotationally fixed manner, and in that a coupling device (9) is provided between the free-wheel (3) and the other of the two screw connection bodies (2). This coupling device serves to connect both screw connection bodies to one another in a rotationally fixed manner and to disengage them from one another.
