`
`1.
`
`A fastening element comprising two legs,
`
`the two legs being interconnected via a web,
`
`wherein at least one leg has at least one recess,
`
`wherein a disk is provided which is mounted rotatably around an axis of rotation in
`
`the web by means of a rotary element,
`
`the disk being designed such that, when rotating around the axis of rotation in a first
`
`position,
`
`it
`
`is arranged between the two legs and,
`
`in a second position,
`
`it protrudes in
`
`sections through the recess,
`
`the disk furthermore comprising at
`
`least one appendage which, when the disk
`
`rotates around the axis of
`
`rotation from the first position into the second position,
`
`is
`
`contacted with a leg prior to reaching the second position.
`
`A fastening element according to claim 1, wherein the two legs each have at least
`2.
`one recess.
`
`3.
`
`A fastening element according to claim 1, wherein in the second position, the disk
`
`protrudes in sections through recesses of both legs.
`
`4.
`
`A fastening element according to claim 1, wherein the disk comprises two
`
`appendages, each of which is contacted with one of the two legs prior to reaching the
`
`second position.
`
`5.
`
`A fastening element according to claim 1, wherein the disk is designed in an oval
`
`shape.
`
`6.
`
`A fastening element according to claim 1, wherein the rotary element comprises a
`
`cheese-head screw.
`
`7.
`
`A fastening element according to claim 1, wherein two legs are arranged essentially
`
`in parallel.
`
`
`
`8.
`
`A fastening element according to claim 1, wherein the web is arranged essentially at
`
`right angles to the two legs.
`
`9.
`
`A fastening element according to claim 1, wherein the rotary element is arranged in
`
`a guide rail.
`
`10.
`
`A fastening element according to claim 1, wherein the two legs project beyond the
`
`web and comprise a bearing section on the side opposite to the disk.
`
`11.
`
`A fastening element according to claim 1, wherein the two legs form an essentially
`
`H-shaped section with the web.
`
`12.
`
`A fastening element according to claim 1, wherein the fastening element comprises
`
`a coupling section.
`
`13.
`
`A fastening element according to claim 12, wherein the coupling section is arranged
`
`on the rotary element.
`
`14.
`
`An assembly comprising a fastening element and a component with an essentially
`
`U-shaped channel,
`
`into which the fastening element can be inserted non-positively in the
`
`second position.
`
`15.
`
`An assembly according to claim 14, wherein,
`
`in the first position,
`
`the fastening
`
`element can be inserted essentially positively into the essentially U-shaped channel.
