A retractile trailer hitch has a tube shaft fixed on a motor-vehicle frame and an arm having a tubular inner end pivotal on the shaft and an outer ball end. The arm is limitedly axially displaceable on the shaft between locked and unlocked positions. Formations on the frame and on the inner end angularly arrest the arm in its end positions in the locked position of the inner end. The formations are unengageable with each other in the unlocked position of the inner end. A bolt is axially displaceable inside the shaft between a holding position and a freeing position. Balls inside the inner end are coupled to the bolt for axially displacing the arm into the locked position on displacement of the bolt into the holding position and for displacing the arm axially into the unlocked position on displacement of the bolt into the freeing position.
