1. A tensioning device, comprising;
a gas generator for generating a pressurized gas,
a piston that can be driven by the pressurized gas,
a tension cable connected to the piston, wherein the tension cable can be connected to a component that is to be set into a tensioning movement and wherein the tension cable extends through the piston,
a guide part arranged on the tension cable on a side of the piston facing away from the gas generator,
a tensioning tube for receiving the piston and the guide part, the tensioning tube having a section forming a curvature, and
further comprising, wherein the guide part and the piston are initially a one piece assembly separated from one another by a predetermined breaking point and wherein the piston and the guide part become detached at the predetermined breaking point upon insertion of the piston and the guide part into the tensioning tube past the section forming a curvature, whereupon the guide part is moveable relative to the piston.
