A securement device for engagement with a cable connector held in a mating socket by a release lever. The device features at least one socket formed into a body which is configured to engage with a cable connector which requires a release lever to maintain the cable connector in the socket. A locking pin engageable through opening on a sidewall is positionable to contact against a shoulder of the cable connector from which the release lever extends to hold the cable connector in the socket until the locking pin is removed. Defective cable connectors lacking an operative release lever can also be held in operative engagement in the socket by the locking pin.
