The invention relates to a fastening device 1 on a hitch ball 10 comprising movable first and second components 11, 12, a jaw formed therebetween being interconnected with each other through an arm 21 and a wedge member 22, the arm 21 being hingedly integrated with the first component 11, the wedge member 22 being slidable and integrated with the second component 12. The articulated arm 21 can advantageously be actuated to translate the sliding wedge member 22 along an inclined face 120 of the second component 12. The wedge member 22 can then be locked in a locked position. Thereby providing a fastening device that effectively clamps a hitch ball under different wear conditions while also allowing for a compact device with a limited profile dimension.
