1. A tensioning apparatus 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 traction cable connected to the piston, the traction cable adapted to be connected to the safety belt component for transmitting a tensioning motion,
a tensioner tube for receiving and guiding the piston,
wherein the gas generator is arranged in the tensioner tube,
the tensioner tube has a cut-out thereof between the gas generator and the piston, and
a cable deflector for guiding the traction cable through the cut-out and out of the tensioner tube, the cable deflector comprising a guide part inserted into the tensioner tube along an extension of the tensioner tube and forming a deflection for the traction cable extending from a piston end of the cable deflector to the cut-out in the tensioner tube, and a fixing part which engages through the cut-out from an outside wherein the traction cable is guided through the fixing part, and wherein the guide part has a cut-out into which the fixing part engages with a projection.
