A pass-thru electrical connector assembly is an integral part of a barrier wall which separates a harsh environment from a controlled environment. A connector body having a staged position and a locked position on the barrier wall has a flange which extends radially outward from one end of an axial projecting portion. Via rotation of the connector body from the staged position to the locked position, the projecting portion of the connector body moves axially forward through a hole of the barrier wall as a ring seal is preferably axially compressed between the flange and one side of the barrier wall. Axial movement of the connector body is achieved via a plurality of locking lugs which protrude radially outward from and are spaced circumferentially about the projecting portion of the connector body. The lugs are aligned circumferentially with a plurality of slots spaced about and communicating with the hole of the barrier wall when the connector body is in the staged position. When the connector body rotates from the staged position to the locked position, the lugs become misaligned to the slots. Simultaneously, a flex lock cantilevered from the projecting portion and disposed between two of the locking lugs snaps radially outward into one of the slots to lock the connector body to the barrier wall.

The device of claim 1, wherein said plug-receiving apertures are located on the body member so that a ground fault disrupter on the plug would be located outside the device when the prongs are inserted within said apertures. 3. The device of claim 1, wherein the body member further comprises an opening to accommodate a ground fault disruptor prong in the plug. 4. A method for securing a male power cord plug with prongs having holes within a body member, comprising the steps of: inserting said prongs of said plug within one end of said body member; inserting a key within another end of said body member; upon rotation of said key, outwardly biasing two outer arm members of a spring, said spring affixed within said body member, each arm outer member having a knob thereon whereby upon rotation of said key within said body member, the knobs of said spring cooperatively engage the holes in the prongs of said plug thereby preventing said prongs from being withdrawn from said body member. 5. A compact locking device for securing a male power cord plug with prongs having holes, comprising: a rigid plastic body having an interior and an exterior surface; said body including a plurality of apertures on a back side of the body, each aperture for accommodating one of said prongs; a key-activated lock assembly accessible on an opposing side of said body for locking and unlocking the plug; an elongated member cooperatively attached to the lock-activated assembly, said elongated member rotatable to a transverse position in relation to the plug when the lock assembly is engaged; and an inwardly biased generally V-shaped spring with a base and two outer arm members, each said outer arm member having an outside section and a circular knob thereon; wherein the base of the spring is attached to the inner surface of the body; wherein the knobs are in cooperative connection with the holes in the prongs when the lock-activated assembly is engaged, and the knobs are released from the holes in the prongs when the lock-activated assembly is disengaged; wherein the apertures are located so that a ground fault disrupter on the plug would be located outside the device when the prongs are within the apertures.
