The invention relates to a tightening device for a safety belt component, comprising a gas generator for generating a compressed gas; a piston drivable by the compressed gas; a pull cord (4) connected to the piston, the pull cord being connectable to a safety belt component displaced during a tightening movement; a tightener tube (5) for receiving and guiding the piston, and a guide block (1) forming a cord guide, in which guide block a receptacle (2) for receiving the gas generator and a pressure chamber (3) fluidically connected to the receptacle (2) are designed, the guide block (1) being connected to the tightener tube (5), the guide block (1) has a pressure chamber (3), and the pull cord (4) extends linearly from the tightener tube (5) through the pressure chamber (3) in the direction of piston movement (6), characterized in that the guide block (1) forms a linear guide (7) which adjoins the pressure chamber (3) and which is designed such that the linear guide (7) extends in the direction of piston movement (6) in the direction of piston movement (6) in the direction of piston movement (6) in the direction of piston movement (6). The guide block (1) is designed such that the pull cord (4) can be led out of the guide block (1) parallel to the direction of movement (6) of the piston on the side opposite the tightener tube (5).
