Abstract: A holding device for holding a structural component for aircraft to a further structural component; may be coupled to one of the components and is moved from a holding mode, where the first component is held to the second component by the holding device, to a release mode using a magnetic force. Furthermore, a method for deinstalling two components is disclosed, where carrying out deinstallation merely requires pressing a first component against a second component, and placing a magnetic key on or over one of the components in the region of the holding device, where at least some method-related steps may take place at substantially the same time.
