Abstract: A fastener for two operating states has a receptacle with a receiving aperture and first fastening means for attachment to a first component. An insertion part with a pin-like plug-in section has, at a fastening end opposite the insertion end, second fastening means for attaching a second component, and can be inserted into the receiving aperture of the receptacle. In a first fastening state, the plug-in section is inserted deep into the receiving aperture and releasably connected to the receptacle by latching first retaining means, which are designed such that the insertion part can be displaced by a release force into a second fastening state. In the second fastening state, the insertion part engages with the plug-in section less deeply in the receiving aperture and is secured in the receiving aperture by second retaining means.
