When you get inside Jeff, the clear plastic you see, is actually just a flexible cover to the fuse.
I found that you could grip this easily with some thin nosed pliers. Bit awkward to get your fingers in there!
My local hardware store found me a couple of these fuses in the bottom of a large box. He had to read each one with a magnifying glass, and it took him half an hour. He then charged me the grand sum of £0.17p!
