1. Apparatus for locking a cable connector in engagement with an external port of a device, wherein said cable connector comprises a plurality of electrical contacts at a contact end configured for contact with port contacts within said external port and a plurality of insulated wires attached to various of said electrical contacts extending from said cable connector at an end opposite said contact end, wherein said cable connector and said port include first attachment means for holding said cable in engagement with said port, said first attachment means being operable to prevent said cable connector from being pulled away from said port and to release said cable connector for disengagement with said port, wherein said first attachment means comprises a screw rotatable in said cable connector and engageable within a threaded hole in a port, with a screw head attached thereto extending from an end of said cable connector opposite to said contact end, and wherein said apparatus comprises:

  • a bracket configured for engagement with said connector, including a bracket aperture through which said insulated wires extend when said bracket and said connector are so engaged;

    second attachment means for holding said bracket and said connector in engagement, wherein said second attachment means comprises a tab, including a slot, extending from said bracket, configured so that, when said bracket is engaged with said cable connector, surfaces adjacent to said slot extend between said screw head and an adjacent back face opposite to a front face of said cable connector;

    a cover configured for engagement with said bracket, including a cover aperture through which said insulated wires extend when said cover is engaged with said bracket and said bracket is engaged with said connector; and

    lockable attachment means for holding said cover and said bracket in engagement;

    wherein said cover, engaged with said bracket, surrounds said second attachment means when said bracket is engaged with said cable connector, to block access thereto;

    wherein said cover and said bracket, when engaged with each other and with said connector, block operation of said first attachment means, thereby preventing release of said cable connector from said port; and

    wherein said cover and said bracket together comprise means for surrounding said screw head to block access thereto when attached and engaged with said connector.
