12v outlet plug fix idea (keep plug backing out)

[**sj**]

what about an "O" ring or rubberband around the plug in...this will seal the moisture out and keep it from backing out ?
If it snugs it right and stops vibrating on and off maybe she wont blow fuses?

The "0" ring sounds like a good idea. The rubber band may not work as well. Sometimes tend to dry out or twist. I like the "o" ring suggestion will try.
