A screening grid for discharging solids from a liquid flow. The grid includes a driveable screening strip that can be inserted into the liquid flow and includes two lateral link chains between which carrying rods extend, carrying groups of adjacent screening links. All screening links include projecting parts that extend respectively only in one direction from a group of screening grids, without being overlapped by the projecting parts of the adjacent group of screening links. All of the screening links of a group are provided with projecting hooks on the outer side of the screening strip.
