To provide a hook fitting allowing a tile to be fixed on the base of a wall surface without a play and the need for an adhesive.

In the hook fitting 20 for mounting the tile 30 having a flat rear surface 32 between an upper engaging recessed part 31 and a lower engaging recessed part 33 on the base B of the wall surface, an upper elastic locking part 21 fitted into the recessed part 31 is formed along an upper edge, a plurality of locking projections 26 fitted into the recessed part 33 are formed along a lower edge at regular intervals, and a flat surface part 24 between the locking part 21 and the locking projections 26 is cut and raised in order to become a pair of elastic projections 13R and 13L pressed against the rear surface 32 of the tile 30. The elastic projections 13R and 13L are protruded forward by a protrusion height ΔH relative to a line connecting the locking part 21 with the front end surface of the locking projection 26.
