1. A chain link of an energy guiding chain, comprising:
at least one plastic injection moulded part in a form of a one-piece plastic body formed of a plastic with a colouration that is a same throughout, which has a first side having a first surface, a second side, and at least one marking visible at the first side,
wherein the at least one marking includes a data code marking with a 2D code that is a QR code,
wherein the data code marking with the QR code is injection moulded as a structure of the one-piece plastic body from a visually black plastic and is machine-readable at the first side, and
wherein the at least one injection moulded part is produced from a fibre-reinforced plastic having a predominant proportion by weight of polyamide with reinforcing fibres.
