Black Box GigaTrue 3 Locking Pins - push-lock pin is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by Josh3807 from I love Blackbox locking CAT6 cables. They keep the public from unplugging the phones we provide as a courtesy. As I cannot remove these phones, I keep them plugged in and hopefully guard them from theft with these locking cables. Two years strong and no calls to plug these back in. Thank you Blackbox!
