Grate wire mesh fastening clip, pre-assembled and screwless, for fastening grid wire mesh to anchor rails. The fastening clip is screwed into the slot in the anchor rail so that both lugs of the clip swing under the bend of the anchor rail. By turning it 90° (across the anchor rail cross-section) around the bottom longitudinal wire of the grid wire mesh to be installed, the movable clip is pressed down with the help of a screwdriver and fixed by turning it 90° under the bend of the anchor rail. An offset arrangement of the fastening lugs on the anchor rails ensures that the grid wire mesh is securely fastened.
