An elongate shaft having a male member of the coupling pair is detachably securable to each of the female members and extends those from along an axis which is parallel to the axis of rotation of the wheel. In response to rotating of the wheel a line, having one end secured to a remote fixed object, is wound about the several shafts to draw the vehicle from a mired location.
