A locking device for at least two adjacent fasteners (e.g. wheel nuts) comprises a ring 2 for engaging the periphery of each fastener and a body 1 which engages the rings 2. A ratchet mechanism 4, 5 is provided between each ring 2 and the body 1 to allow axial rotation of each fastener in one direction but prevent axial rotation of each fastener in a second direction. |
