A fastening arrangement for a safety belt is provided and includes a holder for securement to a vehicle. The holder has a T-shaped head with laterally extending arms. A connector is moveably disposed, against spring action on the holder and is connected to a belt buckle strap loop. A magnet and magnetic field sensor are disposed on the holder and connector. Relative movement between them, caused by displacement of the connector relative to the holder, is converted into a signal that corresponds to acting belt force. First springs are provided on outer longitudinal sides of the holder and connector and respectively extend between the arms of the holder and an oppositely disposed abutment of the connector to counteract tension force of the safety belt or buckle. The compensation spring is disposed between the holder and connector and, without a tension force acting on the connector, prestresses the connector relative to the holder against nearly relaxed first springs with a low spring force.
