The invention relates to a belt winder (10) for a safety belt. The belt winder (10) is provided with a tensioning actuator (30) and a belt winding shaft (20) for winding and expanding the safety belt. The tensioning actuator comprises a gas generator (31), a drive wheel (34) and a feed pipe (32) which is used to connect the gas generator (31) and the feed pipe (32). The feed pipe is provided with at least two thrust portions (300, 300a, 300b) which are accelerated in a thrust direction by triggering the gas generator (31) and the drive wheel (34) for winding of the seat belt. The thrust portions (300, 300a, 300b) are connected positively with each other through a snap connection in the thrust direction. The invention also relates to a method of assembling a tensioning actuator (30) for belt winder (10) of safety belt.
