That would be the anode connection. GI-10 tubes don't have any dedicated anode; your circuit must turn unused cathodes into anodes. So this GI-11 should be considered an improved design. The metal disc is the main anode and the wire running up the side is so that all cathodes are roughly equidistant from at least some point on the anode, which will balance the striking voltages.
