Tip for repairing cables

Just a wee heads-up on a brilliant idea I came across for splicing 2 cables together ....

These genius little gizmos are basically just a piece of heatshrink with 2 small rings of glue at either end and a bit of solder in the middle.
Simple but highly effective and forms a rock solid connection.
Made the job of fixing a dodgy heater cable in my Davinci extremely quick and easy.
Just place the two ends of cable in the sleeve, blast for a few seconds with a heat source and you're done !
