The adjustable fastening device for a bicycle's luggage rack (20) has two downwards extending rods (221,222) with the ends fastened in fitting holes in mounting components (40). Two adapter rails (30) are provided with several spaced apart fastening holes (31), the cross section of which matches the cross section of a through-hole in each mounting component so that the adapter rails can be fitted in the mounting components and fixed in different positions so that the luggage rack can be fastened at different heights relative to the wheel axle.
