PROBLEM TO BE SOLVED: To unnecessitate the arrangement of a supporting element on a plug housing by making a protective flap surely attachable even to a small plug part. SOLUTION: Plug parts have a built-in protective flap 14 which is connectedly attached to a support on the plug housing. The protective flap 14 is attached so as to be movable, When the plug parts are inserted into a socket, from a closed position where the end face of a plug pin is covered to an open position where the end face of a plug pin is exposed. The support, i.e., a guide route is entirely or partly formed out of a guide element 6, which is desirably formed roughly in a U-shaped arch.
