A coupling device for connecting a towed vehicle to a towing vehicle in which the towed vehicle has a towing bar. There is a telescopic arm received within the towing bar with an end of the telescopic arm pivotally connected to an articulating arm. The other end of the articulating arm has mounted to it a trailer hitch adapted for connection to a trailer hitch ball. There is an anti-pivot collar which encircles the point where the telescopic arm and the articlulating arm are pivotally connected. By selectively extending the telescopic arm and moving the anti-pivot collar to permit articulation between the pivotal and telescopic arms, the coupling device can simplify connection between a towed and towing vehicle. There is further provided locking means for securely locking the coupling device in its locked position.
