Lol my old box snapped in 2, I had a few sets of the clips but I have them to mates when there's broke, they do appear on eBay from time to time

I've settled with a bungee cord for now.

The problem is you don't get a choice of box when you go in, I've got a replacement box sitting unused because it's the next version up from the one I owned so it takes a different ammount of tools and sizes which was pretty annoying but was given no choice and took 3 weeks to come In to the store

Take it back to halfords, get a new box. I did

As in the title I like to hang my set up on the wall and the clips have gone on my case
