Source For Cable Couplers?

BTW, I am only looking to couple the inner cable and not the housing.
Actually I am really looking for an inline cable length adjuster to put
in the front der cable between the BB and front der. I am hoping that
some of these cable couplers will be threaded so that I could use it for
fine cable length adjustment.
The existing downtube adjuster rotates with a turn of the headset and
keeps going out of adjustment. This way I would replace the down tube
adjuster with an inline one near the front der.
I would also welcome any other suggestions on how to solve this issue.

There are barrel adjusters that go on the brake hoods where the STI
cable comes out - only works for Shimano of course. Klein uses them
(or used to) because of their internal cable routing - check with a
Klein dealer.

I don't have one in hand, but what about-

a locknut on the downtube adjuster

loctite on it

drill and tap and install a small setscrew in the side of the adjuster
to lock the barrel in position. A 4-40 would handle this small
movement fine, and a 2-56 would probably work. With this, you can
loosen the setscrew to make adjustments.

Not all that unusual. We have both items. write me.

I can't say a cable coupler is the best thing for adjustment. If you really
want a coupler, both Bruce Gordon (http://www.bgcycles.com/access.html) and
DaVinci Tandems (http://www.davincitandems.com/comp.html#inca) have them.
DaVinci also has inline adjusters.

Low-strength loctite on the existing adjuster seems the simplest
route, unless frequent readjustment is needed. Or, remove the
adjuster and gently mash the barrel a bit with a very small hammer to
make it vibration-resistant; when the adjuster is reinstalled, of
course, you'll have to be careful to avoid cross-threading, and you
may expand your vocabulary measurably if you get overenthusiastic with
the hammer. (Try to mash just the center of the barrel, using a
punch, if you use this trick at all, and bear in mind that thereafter,
adjustment will require pliers which will further scar the adjuster.)

You might also get some relief by putting the spring from a carburetor
adjusting screw between the barrel and the adjuster; access to a small
engine shop's junk box is invaluable if this seems likely to be
fruitful.
