Should be easy to make one. You need:
1) An old "busted" atty
2) A SEALED "battery connector" (like from an old battery).
3) Soldering skills - enough to solder a center connector wire on both sides
Use the old atty and solder a wire from center to center (use fairly heavy stranded wire - insulated of course) between the connectors. Make sure the centers connect without touching the outside "ground" - keep the exposed wire as short as possible. The center is the positive lead, the outside "shell" is the ground. Test it for no shorts!! You may wish to use some heat shrink tube. Epoxy works for gluing the parts in, or solder them in place.

Have fun!
P.S. You have to remove the "guts" from the atty. Oh, and use lead-free solder just in case.....
