A tensioning device for a safety belt component, comprising a gas generator for generating a pressurized gas, a piston that can be driven by the pressurized gas, a tension cable that is connected to the piston and is connectable to a safety belt component to be set into a tensioning movement, a tensioner tube for receiving and guiding the piston, and a guide block that forms a cable guide and in which a receptacle receiving the gas generator and a pressure chamber fluidically connected to the receptacle are formed, wherein the guide block is connected to the tensioner tube and the tension cable runs rectilinearly in a piston movement direction from the tensioner tube through the pressure chamber, and wherein at least one damping element is formed, which absorbs the kinetic energy of the safety belt component in the event of a load-free tensioning movement.
