A hitch (10) for coupling a towing vehicle (27) and a trailer vehicle, particularly where the vehicles are misaligned. The hitch (10) has a tongue housing (12) for attachment to one of the vehicles and a tongue (14) for extension and retraction within a throat (23) defined by the tongue housing (12). The tongue (14) articulates laterally to couple misaligned vehicles. T he tongue (14) has a coupler and is movable to a locked position where a spring - biased pin (80) is insertable through apertures (86, 88, 90, 91) in the tong ue housing (12), a lock pin housing (72) and the tongue (14) to lock it in plac e. The tongue (14) and the tongue housing (12) have cooperating guide members (50, 60) to effect a smooth, guided movement of the tongue (14) to its locke d position. The guide members (50, 60) have cooperating, rounded cam members (52, 54, 62) and pockets (56, 64, 66) which facilitate the movement of the tongue (14) to its locked position. Rounded side walls (20, 22) of the tongu e housing (12) guide the tongue (14) during retraction into the housing (12).< /SDOAB>
