A towing device is provided including a bracket (12) and an elongate hitch rod (14). The bracket (12) includes a longitudinal bore (34) and one or more pins (36) oriented transverse to the longitudinal bore (34). An end portion of each pin extends partially into the longitudinal bore. The hitch rod (14) includes a cylindrical shaft (50) and a clevis (52) connected to the shaft's distal end. The clevis (52) is attached to the shaft (50) in a manner that weights the shaft in a desired orientation. The shaft (50) includes at least one groove (60) with a spiral portion (62) and a notch (64). The spiral portion (62) extends from the shaft's proximal end and ends with the notch (64). During use, the transverse pin (36) engages the notch (64), thereby locking the rod (14) with the bracket (12). The weighted orientation of the shaft encourages this engaged arrangement.
