ABSTRACT:
An electrical plug-coupler-system with a cylindrical plug socket comprising a collar with an external thread, the coupler of which engages in the collar and can be fixed with a cap on the external thread of the collar. The technical problem is the sealing of the interior against emerging oil and against entering water, especially pressurized water at diving pumps. The insert sleeve of the plug socket has several barbed tongues at a front ring, the ridges of the tongues facing an end shoulder of the collar by leaving a peripheral gap open which receives an inner edge of an installation hole as well as a sealing washer. A nut is screwed firmly onto the external thread of the collar for fixing the sealing washer. The coupler cap tightens the front edge of the collar by a ring surface.
