A connecting means for ignition systems in internal combustion engines is designed such that the connecting means is functionally reliable even under unfavorable operating conditions. The connecting means has, among other things, a first connection for an ignition coil, a second connection for a spark plug, and a covering cap encasing these connections. The covering cap is made of two layers, having an inner casing made of electrically insulating material and an outer casing lying directly on the inner casing, the outer casing being made of an electrically conductive material, which is electrically connected to ground potential. The casings are each made up of a resilient material. The connecting means is for use in the automotive industry.

The part of the distributor electrode in the breakdown region has a resistance of at least 400 ohms per millimeter. The total resistance of the electrode is in the range of between 0.5 and 1.0 kilo-ohms. The material is a mixture of a resistive ceramic material and a finely dispersed additive of metallic conductivity. Arrangements for creating surface discharge gaps thereby slowing down the sparking process and decreasing interference are also illustrated.
