Abstract
A telephone cord includes a length of cordage having each end terminated with a modular plug with the plug at one end disposed within a specially designed, easily identifiable cavity of a unipartite housing of a coupler jack of this invention. The coupler jack also includes a conventional plug-receiving cavity and a plurality of wire-like contact elements having retroflexed end portions which are positioned in the cavities to engage terminals of inserted plugs. The plug that is disposed within the specially designed cavity is held in such a manner that its disconnection from the coupler jack is encumbered to prevent withdrawal without the use of a mechanical expedient. Forces must be applied to a tab of the plug in a particular manner to cause the tab to assume an essentially linear rather than a conventional arched configuration which occurs when the free end of the tab is depressed. Also, the specially designed cavity is substantially deeper than the conventional cavity so that the inserted plug does not extend to the external surface to which the cavity opens. This prevents digital depression of the locking tab at its free end and the arching of the tab which in a conventional cavity permits withdrawal of the plug.
