I don't know what a Tomic connector is either.
What I suggested was a Tomic coupling. It is the same as a rigid pipe
coupling (or galvanized water pipe coupling for the
not-electrically-inclined), but instead of being 1.5" long for 1/2" pipe
it is half that length.
What I suggested is that you can make any "gofrom" - like sealtite to
flex, by screwing a sealtite connector in one end of a rigid coupling
and a flex connector in the other end. The short Tomic connector just
makes a neater transition with less likelyhood of a fishtape hanging up
between the connectors. "Tomic" works at the wholesalers around here,
but may be local jargon, as someone said.

It sounds to me like you may be referring to what we call an Erickson
coupling.

An Erickson is a 3 piece rigid coupling that is the electricians version
of a plumber's union fitting. (I think they used to be called a "swede"
around here.)
I am just talking about a garden variety threaded rigid pipe coupling
except it is 1/2 length. I wouldn't use it to join rigid pipe, but it
can be handy in other applications.

That's what John and I found with a Google search, but that's a range or
dryer cord connector, not what Bud was describing
