I think you are talking about the plugs that actually go into the receiver, right? I have to say that I have never had a plug pull out of the receiver, and the only way it might even be a slight possibility is if the receiver or something else came loose and started yanking on a wire. This is a high improbability, but still a remote possibility. So, once I get all my wires plugged into the receiver, I run a thick bead of silicone across all of them, essentially tying them together. This way, if one plug, for whatever reason, wants to come out, it's gonna have to take the rest of the plugs with it!
