NEW Electrical connector - seen on TV

[2Dogs]

Hey All,
Watching one of the hot rod shows over the break and at the end of the show they had a new(?) type of electrical connector - waterproof, reusable thread type, doesn't need soldering or crimping etc....
Looks like an in-line fuse connector.

Anyone seen them for sale? What brand are they? I checked a few parts stores but no luck yet.

Thanks,

They have been out for quite a few years now... Posi-Lock connectors.

They work as advertised?

Got one of my alternator to battery cable. Working fine so far.
