The invention contemplates a rotatable electrical connector having an inner tube and an outer tube surrounding the inner tube, wherein the inner tube and the outer tube are rotatable relative to each other about a common longitudinal axis. The joint housing for the plug contacts is on one end end of the two tubes and the module housing is on the other end of the two tubes. At least one protruding first latch member engages into at least one first recess when the two tubes reach a predetermined rotation angle. In addition, there is a flexible electrical conductor in the internal space of the inner tube.
