The present invention discloses a safety venetian blind including an upper groove, a bottom beam, and a plurality of slats disposed between the upper groove and the bottom beam. A first driving device is disposed in the upper groove for driving the slats to rotate via a ladder tape connected with the slats. A second driving device is disposed in the upper groove for driving the bottom beam to move up and down via a lift string connected with the bottom beam so that the slats are closed and opened. The lift string passes through the slats. The slats has at least two string loops respectively provided at opposite sides of one of the slats, and a first side portion of each of the string loops is fixed with the cord while a second side portion of each of the string loops wraps the lift string for at least one loop.
