Abstract
A tow-bar having a skeletonized tongue portion is described. A stopper is typically includes on the bottom portion of the tongue. A head piece having handles internal to the head piece is connected to one end of the tongue. The handles are typically positioned in a triangular arrangement. The end of the tongue, opposite the end including the head piece, includes a hinging portion that can be connected to the respective cart having the tongue. The hinging portion and the head piece include “keyed” ends so that they can connect to the tongue like puzzle pieces. These keyed portions are welded to the tongue. In this way, the pull points are not straight welds but rather keyed and welded portions thereby able to withstand typical abuse.
