The present invention relates to a joint apparatus of car windshield wiper arm, which comprises a gripping cabin and a chassis; wherein, said gripping cabin having a hollow opening perforates through at the junction of the top surface and the front side; a vertical elastic hook is erected at the center of said hollow opening; and a pair of snap-on lugs are outwards respectively protruded at two junctions in the left side and right side of said gripping cabin with the rear side. By means of said vertical elastic hook and two snap-on lugs buckling engagement with the front tab and two bottom flaps on the head of said wiper arm, the rigging joint between of said wiper and said wiper arm become more securely firm; Besides, in the practical operation of dismantling and replacing worn wiper by new one, the separation of said wiper from said wiper arm can be easily, simply and rapidly accomplished by directly applying force on said vertical elastic hook with only one finger.
