Review on RJCLIP - Ultimate RJ45 Connector Fix (5 Pcs: Assorted Black/Silver/Blue/Yellow/Clear Colors) by Hamilton Larcony

The description does not mention that these clamps will not work without operation on the clamp if your defective plug has a protector/strain relief protector. If your boot slips back you're in luck, if not get out your Xacto knife because you'll have to cut the boot off. I decided against it because I was concerned it would weaken the cable connections to the plug and my cable is expensive and of little use if broken.
