Wheel lock with central expander

A main module adapted to be attached to a wheel of a vehicle, the main module being configured to be fitted with a protective case for covering a nut or a bolt for attaching the wheel;

• wherein the main module comprises:
• a centre bolt adapted to be connected to the main module by threading such that the axial position of the centre bolt, as seen along the axis of rotation of the wheel, is adjustable at a time of attaching of the main module to the wheel by rotating the centre bolt relative the main module;
• an annular expander adapted to be operably connected to the centre bolt such that the annular expander expands in a radial direction of the wheel as the axial position of the centre bolt is adjusted at the time of attaching of the main module to the wheel, such that the annular expander engages with the wheel and thereby secures the module to said wheel;
• and
• a locking mechanism adapted to be arranged in a locking state in which the locking mechanism prevents the centre bolt from rotating relative the main module, and in an open state in which the locking mechanism allows the centre bolt to rotate relative the main module, wherein
• the locking mechanism comprises an axial recess formed in the centre bolt;
• a detachable socket having a through hole and being adapted to be rotationally secured to the main module;
• and
• a detachable locking bolt adapted to be inserted into the main module via the through hole and the axial recess;
• and the axial recess and the through hole are configured to be aligned with each other, and
• the locking bolt is adapted to prevent the centre bolt from rotating relative the socket.
