The invention provides in a best tensioner (10), especially a rotary tensioner, for a seat belt comprising an elongate and preferably cylindrical pressure cylinder (129, a piston (18) movably supported in the pressure cylinder (12) in the longitudinal direction which is adapted to be pressurized with fluid under pressure and thus to be moved into a tensioning direction (S), a thrust means (20) interacting with the piston (18) and a stop (24) provided on the inside (38) of the pressure cylinder (12) to which the piston (18) can be adjacent in the tensioning direction (S) at an end position at which the piston (18) seals the pressure cylinder (12), that the stop (24) is made of a plastically deformable material and is plastically deformed by the piston (18) at the end position so that the piston is in sealing contact with the inside of the pressure cylinder (12).
