A tow bar holder for securing a tow bar to a boat having an outboard engine has two separate securing elements secured to the stern of the boat. The securing elements each have a fixing element for securing to an engine plate, and a receiving element. The feet of the tow bar can be plugged into a receiving space of the receiving element. In this case, the internal dimensions of the receiving space are larger than the external dimensions of the feet of the tow bar, such that the tow bar is tiltable and/or is fixable in various positions in the receiving space.
