A fastening element comprises a first clamping element and a second clamping element rotatably mounted about an axis of rotation on the first clamping element. The first and second clamping elements each have a first or second lever section, which extends essentially perpendicular to the axis of rotation, and a first or second connecting section, which extend away from that essentially parallel to the axis of rotation. The first lever section and the second lever section are moveable relative to one another about an axis of rotation between a splayed lever position and a non-splayed lever position. The first clamping element and the second clamping element are configured to hold the article when the first lever section and the second lever section are located in the splayed lever position, and to not hold the article when they are located in the non-splayed lever position. The first and second clamping elements each comprise a first or second support section, which extends essentially perpendicular to the axis of rotation, is connected stationarily to the lever section, and extends at an obtuse angle to the lever section. The first support section and the second support section are located in a non-splayed support position when the first and second lever sections are located in the splayed lever position. The first and second support section are located in a splayed support position when the first and second lever sections are located in the non-splayed lever position.
