A safety device for a pneumatic nailer includes an attached tube connected to the magazine of the nailer and including a first passage for movably receiving a first pine and a second passage for movably receiving a second pin. A driving piece is pivotably connected to the attached tube at a mediated point of the driving piece. A spring is received in the second passage and biased between a closed end of the second passage and a first end of the second pin. A second end of the second pin is retractably extended through an open end of the second passage by the spring and can be inserted in a locking hole of a safety bar movably connected to the barrel of the nailer. Two ends of the driving piece are respectively connected to the first pin and the second pin such that when no nails are located in the barrel, an end of the first pin is extended into the magazine while the second pin is inserted in the locking hole of the safety bar to lock the safety bar.
