Abstract

A central locking arrangement for wheels of motor vehicles with a centrally aranged threaded bush which is connected with a joint shaft, whereby the bush retainingly receives the wheel under interposition of a wheel hub. An anti-rotation protecting sleeve which is arranged inside of the threaded bush is connected with the joint shaft and the bush. The anti-rotation protecting sleeve is form-lockingly connected with its free end opposite the joint shaft with a lockable anti-threft protecting lock adapted to be inserted in the bush. The threaded bush includes a longitudinal bore with a polygonally shaped section that serves for the work-tool engagement and in which the protecting sleeve is retained by way of a corresponding outer contour.
