A device for carrying a rail car coupling knuckle. The device includes an open end, a closed end and a retaining pin for securing the open and closed ends together. The open end includes a pair of substantially parallel tubes that are fixedly attached to a metal plate. Preferably, the tubes have substantially equal inner diameters. One of the tubes has a flange near one end and an opening near the other end. The closed end includes a pipe and a tube that are fixedly attached to a metal plate. Preferably the pipe and the tube of the closed end is substantially parallel to each other so as to be in alignment with the tubes of the open end. The outer diameter of the pipe of the closed end is slightly smaller than the inner diameter of the tube of the open end. Likewise, the outer diameter of the other tube of the open end is slightly smaller than the inner diameter of the tube of the closed end. In this manner, the pipe of the closed end can be inserted into the tube of the open end, and the tube of the open end can be inserted inside the tube of the closed end while one of the tubes supports the rail car coupling knuckle. The retaining pin can be inserted into openings in the tubes to hold the open and closed ends together while carrying the rail car coupling knuckle.
