A cable extends externally from the frame and socket. The housing has a first opening that exposes the cavity and a second opening through which the cable passes. A pair of spaced apart tabs formed on the exterior of the housing are secured by a tie wrap or bracket to a telephone set to mount the jack thereon. The housing comprises a lower portion and an upper portion that lock together when the housing is assembled. One of the portions has a first interior partition with a straight edge, the other portion has a second interior partition having in abutment with the straight edge of the first partition an edge with an arch-shaped opening.
