An actuator, comprising: a housing, comprising a single part in the shape of a hollow cylinder, having a connecting end and an actuating end; a hollow cylinder-shaped cover, molded or bonded around the connecting end of the housing; a piston with a pin, disposed in the housing, and displaceable in a longitudinal direction of the housing; and an igniting element with contact pins, aligned in a longitudinal direction of the housing; wherein at least a portion of the contact pins of the igniting element project out beyond both the cylindrical cover and the connecting end of the housing; wherein before the igniting element is ignited, the pin of the piston does not project out beyond the actuating end of the housing; and wherein when the igniting element is ignited, propellants generated by ignition of the igniting element displace the piston in the direction of the actuating end of the housing, until the pin of the piston projects out beyond the actuating end of the housing.
