Plug connector device having a wiring block with at least one receiving region

A plug connector device includes one or more wiring block(s) which is provided for receiving one or more multi-wire data cable(s). The wiring block includes one or more receiving region(s) for receiving one or more wire(s) of the multi-wire data cable(s). The receiving region is at least partly delimited by one or more receiving element, which is at least partly deformable. The one or more receiving element(s) includes one or more first receiving piece(s), which is implemented at least partly elastically and/or plastically deformable. The receiving region(s) includes one or more second receiving piece(s) including one or more holding lug(s), which is at least partly provided for fastening respectively one wire of the multi-wire data cable(s) in a form-fit manner. The first receiving piece at least partly has a first rigidity, the second receiving piece at least partly has a second rigidity different from the first rigidity.
