Abstract
For the purpose of providing a simplified manner for the production of a joint between a transverse link and a link plate for a chain link of an energy guide chain, it is proposed that the link plate has a fixing means which is suitable for and intended for separable joining of the link plate with a transverse link. The fixing means has at least one locking means. Furthermore, at least one torsional element is provided. This is joined to the fixing means and a wall of the link plate so that it can be pivoted essentially around a longitudinal axis of the link plate. For releasing at least one transverse link, the at least one torsional element is twisted essentially around a longitudinal axis of the link plate. Through this design of a link plate according to the invention, safe and reliable joint between the link plate and a transverse link is made possible.
