The present invention relates to a waterproof panel fixture. According to the present invention, the present invention relates to a waterproof panel fixture wherein a waterproof panel is combined with a horizontal bar provided in parallel with the front of an underground wall. In the waterproof panel, an insertion groove in a vertical direction is formed at the vertical end of both sides. The fixture is formed in the upper end and the lower end of a fixture body to allow a locking finger to be separately extended to the rear side. An inserting piece is integrated with one side or the other side of the fixture body to be inserted and fixed into the insertion groove of the waterproof panel. As the rear surface of the fixture body comes in contact with the horizontal bar, the end of the locking finger is locked in the upper and lower edges of the horizontal bar. The present invention has effects of reducing the number of components and improves workability by allowing the easy combination of a waterproof panel with a horizontal bar by a waterproof panel fixture and preventing separation when a waterproof panel is pulled out from the front surface or the front side.
