Abstract
A balloon closure head for mounting a balloon and a lamp for illuminating the balloon, as well as apparatus for conducting air to inflate and deflate the balloon and apparatus for conducting electricity to the lamp. The conducting apparatus employs needle nose piercing elements which pierce supply channels for both gas and electricity carried by rectangular conduits sealably clamped to the closure head. In one embodiment, a single pair of conductive hollow needle nose piercing elements and cooperating non-return valves supply both gas for the balloon and electricity for the lamp.
