1. A fastening device for fastening add-on parts on carrier components, wherein the fastening device has a plug-in locking device, for locking to a carrier component, and a releasable rotary locking device, which is spaced apart axially from the plug-in locking device and is intended for locking to an add on part, wherein the rotary locking device has an axial supporting element and at least one locking wing, which is spaced apart axially from the supporting element and extends away radially from an axial shank of the fastening device, wherein the supporting element and the at least one locking wing have axial locking surfaces, which are located axially spaced apart from and opposite one another to define a space therebetween, wherein the axial locking surface of the supporting element is arranged axially between the locking wing and the plug-in locking device, wherein the rotary locking device also has a rotary locking stop, which delimits the rotating-in and/or rotating-out action; wherein the rotary locking stop is a crosspiece that extends (i) radially with respect to the axial shank and (ii) axially from the axial locking surface of the locking wing to the axial locking surface of the supporting element.
