An apparatus is provided to facilitate connection inspections for a high tension cord 1. The apparatus includes a contact element that can be brought into contact with a distributor terminal T2. The contact element includes elastic elements 31b to 34b that are constructed to be displaceable between an enclosed state where they enclose the distributor terminal T2 to establish an electrical connection therewith and an open state where a high tension cord 1 can be mounted and detached. Since the distributor terminal T2 can be connected electrically without precisely positioning it, connection inspections for the high tension cord 1 can be made easier and, consequently, automation and labor-saving can be made possible.
