ABSTRACT:
An adapter (11) for connecting each of two telephone cords (12) to a wall terminal (14) includes a housing (16) having two stacked cavities (54-54') at one end, with each cavity being capable of receiving a modular plug (13) that terminates one of the cords and each communicating with a plug portion (17) that extends from an opposite end of the housing and that is insertable into the wall terminal. The adapter includes a plurality of wire-like contact elements (20) with each having a retroflexed portion for electrically engaging a contact (34) of the wall terminal when the plug portion is inserted thereinto, and each having free ends that extend into the cavities at the one end of the housing to engage blade-like terminals (21) of the modular plugs which are inserted into the cavities.
