Have an old appliance with a broken control cable that looks like a bicycle
brake cable except the head part, so I can't replace it with a bike cable.
But is there a way to join two such cables at mid point?

Perhaps I could crimp the cores of the cables. But the crimped portion no
longer fits into the cable shell, I'd need something else to join the
shell...

It is called a Bowdan cable. Some are stiff enough to function in
both push and pull like a lawn mower throttle, some tend to work
one way with spring pressure moving the other like a bicycle
brake. If it needs to stay in the sheath, you will be better off
replacing.

I agree that it's hard to tell what you need without knowing more or
better yet seeing more.

However if you mean what I think you do by shells, you don't have to
connect the shells (the tubes?) Look at the gear cable on many or all
3-speed bikes. There is only an outer case on the part from the
control to the frame near the front fork. After that it is just a
cable, with a pulley on the frame below the seat.

If you are only pulling and not pushing, if there is a spring that
pulls it back, if first the cable can't go in a straight line to its
end, you just need a place to mount the far end of the first shell.
From there the cable can go on and be spliced to the start of the
second cable. The second cable probably doesn't need to have a shell
at all. Like on a bicycle, you can use a pully (or a sleeve, part of
the cable shell) to go around corners. Or if the path is still not
straight, you can fashion a bracket to hold the shell for the start of
the second cable, but it doesn't have to connect to the shell of the
first cable. Maybe you can lower the number of corners.

For connecting the cables they have bolts with a slit down the middle
and a nut that clamps on the wires in the slit. I don't know if they
come as small as you would want or not.
