A chain including chain-link units pivotally connected with each other. Each chain-link unit includes two lateral plates, a first link plate and a second link plate. Two ends of the lateral plates are defined as a first end and a second end. Two first pin-joint parts are configured near the first ends of the lateral plates respectively, and two second pin-joint parts are configured near the second ends of the lateral plates respectively. The chain-link units are pivotally connected with each other via the first pin-joint part and the second pin-joint part. Thus, the chain-link units are common, and each can be the starting chain-link unit, the middle chain-link unit or the ending chain-link unit. They can be easily assembled without screws, which further reduce the time consumption. Moreover, the noise made as the chain works can be reduced, and a buffering function can also be provided.

An energy guide chain including two plate comprising successive chain plates which respectively partially overlap with each other in overlap regions. A respective side part of plastic is associated with each second chain plate. The chain plates are made from a different material from the side parts and have through apertures in their overlap regions. In its two end regions each side part has a plurality of projections which respectively engage through the overlapping apertures in the associated chain plate and the respectively adjoining chain plate to limit the relative pivotal angle of successive chain plates and/or to connect same. In addition there is proposed a two-part separating web for an energy guide chain, wherein the first part has at least one securing pin and the second part has at least one securing receiving means so that the two parts can be connected and released in a direction perpendicular to the main plane of the separating web.
