A conductive lower shell is provided having sides, a bottom, a front face and a rear wall. The sides of the lower shell include recesses formed in edges thereof. Flanges are provided on the sides of the upper shell. The flanges have tabs extending downward therefrom. The tabs are received in the recesses in the edges of the sides of the lower shell when the upper and lower shells are joined. The recesses hold the flanges against the sides of the upper shell. A connector assembly is provided comprising an upper shell having a top, sides, a front face and a back wall. A lower shell has sides, a bottom, a front face and a back wall, wherein the front face of one of the upper and lower shells includes a pin and the front face of another of the upper and lower shells includes a cross member. The pin is held by the cross member to retain the front faces of the upper and lower shells joined with one another. The shells enclose a printed circuit board with an exposed end for connection to a mating connector.
