The invention relates to a circuit breaker for electric supply lines, in particular energy lines or battery cables of motor vehicles. Said circuit breaker comprises a first connection element ( 2 ) and a second connection element ( 4 ), the current path running between the first connection element ( 2 ) and the second connection element ( 4 ), when the circuit breaker ( 6 ) is in a conductive state. The aim of the invention is to provide a cost-effective, fail-safe circuit breaker. To achieve this, the first connection element ( 2 ) comprises a cavity ( 8 ) and the second connection element ( 4 ) is configured from an electrically conductive flat part and the second connection element ( 4 ) has a projection ( 10 ) that corresponds to the shape of the cavity ( 8 ), in such a way that in the conductive state of the circuit breaker ( 1 ), the projection ( 10 ) rests in the cavity ( 8 ) in a non-positive fit.
