摘要

An adaptor part (30) is arranged between a plug attachment (6) and a plastics holder (2). The adaptor part is fixedly attachable to the plastics holder. A rotation prevention mechanism is formed between the adaptor part and the plug attachment. The core (23) of the plug attachment is linearly retracted into a receptacle chamber (31) of the adaptor part during the screw-in process. At least the core of the plug attachment has a non-circular cross-section.
