Electrical connectors/insulators

[trilinearmipmap]

Can anyone give me some advice on wire connectors which also insulate.

I have used plastic wire nuts which hold the wires together and also provide some insulation against direct wire-to-wire contact.

When I took apart my strip-light to replace the ballast, the wires are held together by a plastic thingy that seems to hold them really tight and also looks like pretty well a moisture-proof seal. This looks like a rectangular plasting thing which snaps shut and I can't get it open.

Anyone know what these things are and where I can get them, I need to attach three wires together inside my strip light.

I'd suggest soldering the connections and using heat shrink tubing to insulate and seal them.

you can do what is advised above and it is best (with heat shrink that has a glue in it for water tight seal)
but most do not have the tools for this. I have a supplier that provides me with wire conectors that have solder built in and heat shrink, it all can be done with a hair dryer.
If you would like more info just pm ne
