A safety device for infant protection includes a body having circular holes on both sides and a bent part in the center thereof to be bent at different angles, which is provided with a reinforcing wall formed with a predetermined height around the entire periphery thereof. Two knobs, each having a flat bottom surface and a screw rod composed of an idle part and a male screw at a predetermined length and projected from the center portion. An outer diameter of the screw rod is larger than a diameter of the circular hole while a diameter of the idle part is smaller than the diameter of the circular hole, whereby the knob can freely rotate without escaping and being disassembled from the circular hole when the idle part of the screw rod is inserted into the circular hole.
