A blind includes a headrail, a bottomrail, a plurality of slats positioned between the headrail and the bottomrail, a plurality of ladders, a plurality of lift cords and a plurality of connectors. Each ladder is composed of two vertical portions and a plurality of rungs in parallel between the two vertical portions. The lift cords are positioned at two opposite sides of the slats and near the vertical portions of the ladders. Each slat has at least a hole near a longitudinal side edge, and a connector is deposited between the ladder and each slat. Then the connectors can combine the ladders and the lift cords with the slats in such a way that the slats can be kept from moving so as to shut off light effectively.
