The first fastening element (13) and the second fastening element (15) are configured to be connected to rails (41) on a cabin floor (45) of the means of passenger transport (5) and to be displaced in the rails (41). A first joint element (17) is arranged between the first fastening element (13) and the second fastening element (15) such that a spacing (19) between the first fastening element (13) and the second fastening element (15) is variable.
