The invention relates to a tap hole plug gun (1) for metallurgical furnaces, having a pressure cylinder (2) for receiving the plugging compound, which has a closable filling opening (3) for the plugging compound, and having a plugging piston for pressing the plugging compound out from a mouthpiece (6) of the pressure cylinder (2) pressed against the tap hole of a furnace. The pivotable safety flap (4) for closing the filling opening (3) of the pressure cylinder (2) for the plugging compound is equipped with a stop (8), which is pivoted into the cylinder chamber (9) of the pressure cylinder (2) upon opening of the flap (8) to decelerate an unintentional forward stroke of the plugging piston for pre-compression and expulsion of the plugging compound, and is pivoted out of the cylinder chamber (9) upon closing of the safety flap (4). |
