I must have seen “plug connector” a million times as the translation for Steckverbinder. Sometimes more is less and an average English engineer doesn’t need or want to know whether an electrical connection is made by screwing or pushing. The presumption is that you push plugs into sockets, or in the hermaphrodite world of car electrics you simply connect the connectors. Screwing cables together would do nasty things to the wires, not to mention the impossible complexity of numerous precision slip rings that would be required for screw fit multi-way connectors.

Just connector is quite enough.
