A hitch device adapted to be mounted on a draft vehicle for towing a trailer vehicle having a tongue with a latch pin hole, including a rearward biased yoke member normally engaging and retaining a downward biased latch pin in an elevated armed position. When the draft vehicle is moved rearward toward the tongue, the yoke member is engaged and thrust forward by the tongue to release the latch pin which is thrust downward through the aligned latch pin hole in the tongue. Remote-control means are provided for elevating the latch pin in order to unlatch the draft tongue.
