An electrically insulating sheath is attached and engaged with the engaging surfaces of the insulating caps at the engaging surfaces at its opposite ends so that at least one cylindrical engaging interface is defined therebetween. An electrical conductor is supported by and extended through the insulating sheath for electrically connecting the ignition coil and the high voltage terminal of the spark plug to each other. The electrical connector also comprises an electrically insulating structure, disposed in the engaging interface between the engaging surfaces of the caps and the sheath, for providing additional electrical insulation in the engaging interface. The insulating structure may be a circumferential annular ridge and groove in the engaging interface, an electrically insulating bonding agent disposed in the engaging interface, an axially extending annular wall and groove, or a circumferential annular space defined in the engaging interface between the engaging surfaces and a volume of electrically insulating bonding agent filled within the annular space.
