Abstract: An apparatus for receiving an RJ series plug and making electrical connection with at the contacts on the plug and conveying any signals on the contacts to a communications device such as a telephone, facsimile machine, modem, or a local area network adapter. A body includes one or more recesses which receive the plug. An expandable and stretchable membrane isolates the contacts in the plug from electrical contact with an object in a surrounding environment such that passage of current from one or more of the electrical contacts to an object present in the surrounding environment is prevented. A removable shell is provided into which the body is slidably held within the communications device. The removable shell allows the shell and the body to be easily replaced. Another body can be pivotally attached to the communications device such that the body is rotated into and out of the communications device for storage and use.
