Abstract: A fastening apparatus includes a head element for abutting a first edge region of a component opening and an anchor foot element for rear engagement with a second edge region lying opposite the first edge region. The anchor foot element has a base section extending from the head element in axial direction and four locking arms arranged in pairs and connected to the base section. Each pair of locking arms is configured in order to be pivotable relative to an axial central plane of the fastening apparatus, and each pair of locking arms has locking/centering stages arranged offset from one another in axial direction. A locking/centering stage comprises a centering surface for centering the fastening apparatus relative to a component opening and a locking surface for rear engagement with a component opening. A locking surface and a centering surface of a locking/centering stage are arranged approximately orthogonally to one another.
