A see-through housing fabricated from tamper-proof material is pivotally mounted relative to the undersurface of a flat mounting plate the dimensions of which are such as to exceed the spacing between pairs of adjacent joists or studs in the walls or ceiling of a building, said plate being anchored to said joists or studs by means of fastener elements which are, preferably, thereafter rendered irremovable. An opening is provided within the plate for providing access to an electrical outlet or the like which projects through said opening, said outlet being visible when enclosed within the housing.
