Known ignition coils have a high-voltage connection, a spring for electrically connecting the high-voltage connection to a spark-plug and an elastic protective jacket that surrounds the spring. The windings of the spring lie in a block against one another in a block section that faces the high-voltage connection and are interspaced in a spring section designed to contact the spark-plug. To permitthe ignition coil with the elastic protective jacket to be pushed easily onto the spark-plug, said protective jacket is reinforced by the integration of two metal sleeves.
