The invention relates to an actuator assembly for an airbag module in a vehicle safety system comprising an actuator () and a tensioning means (), wherein the actuator () includes a release member () which in the idle state of the actuator is connected to a retaining member () and is separable from the retaining member () by actuating a pyrotechnical ignition unit of the actuator () along a predetermined breaking point () so as to release a loop () of a tensioning means (). The invention excels by the fact that the loop () is formed between two tensioning means portions () which are interconnected directly at the predetermined breaking point () by a connecting means () such that the loop () is tensioned around the predetermined breaking point () in a self-fixing manner. Furthermore the invention relates to an airbag module, a vehicle safety system and a manufacturing method.
