An interlocking mechanism positioned intermediate each end of a drawbar member portion of a slackless drawbar assembly which includes an elongated member engageable at a first end thereof to an end of a first male connection member and at an axially opposed second end to an end of a second male connection member of such drawbar assembly. At least one of such elongated member and such end of such first and such second male members include at least a hollow portion so that one of such elongated member can be disposed in such at least a hollow portion of such end of such first and such second male members, and such end of such first and such second male members can be disposed in the at least a hollow portion of such elongated member. A first aperture, having a first predetermined shape, is formed through the elongated member adjacent at least one predetermined first end and such axially opposed second end thereof. A second aperture, having a second predetermined shape, is formed through a respective one of such end of such first and such second male members. A plate like connection device, having a third predetermined shape, is disposed in each of such first aperture formed through said elongated member and said second aperture formed through such respective one of such end of such first and such second male members for connecting such elongated member to such end of such first and such second male members.
