Abstract A convertible handle for a cargo vehicle can be used for manually pushing the vehicle or for connecting the vehicle to a tractor. The handle has a towing part that can be used either as a stand or a towbar, and a grip part that can be used either as a grip or as structural support for the vehicle body. The handle rotates from one position to the other, pivoting about a pivot on the vehicle body; and, screws or the like fix the handle in the desired position.
