The cover is a one-piece molded plastic part that has a covering portion comprising an end wall that is disposed in end covering relation to the end of the hitch tube and an integral attaching portion that projects from a central region of the cover end wall for releasably attaching the cover to the hitch tube. The cover further includes a top wall and side walls that are in top and lateral covering relation to the hitch tube. It also has a partial bottom wall that is an underlying relation to the hitch tube but contains a centrally located notch that provides access to the attaching portion for unlatching the attaching portion from the hitch tube when it is desired to remove the cover. The attaching portion comprises a tubular wall fitting closely into the hitch tube and an integral catch that snaps into a hole in the hitch tube which is used for pinning the drawbar to the hitch tube when the drawbar is in use. The cover also contains covering provisions for covering safety chain attachment holes that are provided to either side of the hitch tube. Advantageously the cover is fabricated as an injection molded plastic part from a tough, durable plastic such as polypropylene.
