A plurality of locking members are integrally attached to the outer wall at each half to mate with a locking receptacle attached to the inner surface of the outer wall of the mating half section. An inner core of a metallic material is incorporated into the outer wall, the top and the bottom to increase the difficulty of penetration through the surface housing.
