ABSTRACT:
In an energy supply chain for receiving cables, hoses and the like, the chain links are made box-shaped and are provided alternately with studs and circular orifices on their side walls, and consist entirely of plastic material, without the use of additional connecting elements. Each chain link consists of a pair of mirror-inverted side plates and of a pair of identically equal crosspieces, all of which made of plastic material. In a modified embodiment only the side plates of every second chain link are connected to one another by means of crosspieces, while the side pieces of the intervening chain links carry fork-shaped projections for receiving a flexible band. The afore-said two bands extending on both sides of the energy supply chain and over the entire length of the same, cover the interior against dirt or water splashes penetrating from outside.
