ABSTRACT:
The invention relates to towing couplings of a type comprising a fixed part and a moveable keeper which are together adapted to clamp on a tow-ball when the keeper is in a locking position but which are adapted to release the tow-ball when the keeper is moved to an unlocking position. A towing coupling according to the invention has a cam engaged with the keeper, a single spring urging the keeper away from its locking position into engagement with the cam, the spring also urging the cam in the direction of motion which causes it to apply a force to the keeper urging the keeper towards the locking position, and a lever connected to the cam for moving the latter against the action of the spring to allow the keeper to move away from the locking position.
