ABSTRACT:
Components must often be released again from their holder for maintenance. Since the fastenings are often very complicated, it takes a considerable amount of time to release them. A fastening system is one where components can be fastened in a rotationally locked manner to a holder, and released again in a simple, reliable and quick manner.
