In order to prevent theft of a vehicle, there are a number of available arrangements, more or less effective. The present invention will, in the event of unlawful driving of a vehicle, cause one or more tyres to lose their air, so making driving impossible. This is achieved by screwing tight, on one or several wheels 1 and 2, a device 4 on the wheels' 1 and 2 valve nipples 3, and after that locking the device 4 with a lock 5-6. In its locked position, the device 4 is ready to depress the valve nipple 3 pin on movement of the wheels 1 and 2. <IMAGE> |
