A chain for suspending an article, while concealing electrical conductors leading to the article, comprises a series of interlocking links, each link having a tubular portion through which a conductor can pass. Each link has an inlet aperture and an outlet aperture for the conductors, these apertures being located at opposite ends of the link, and both apertures being on the inside of the link. An outlet aperture at the lower end of an upper link underlies and registers with an inlet aperture at the upper end of the next lower link, so that a conductor can pass upwardly out of the outlet aperture of each upper link and into the inlet aperture of the next lower link without being exposed to view, the conductor then passing through the tubular portion of said next lower link to its outlet aperture and thence into a further lower link.
