I know that ford europe along with a bunch of other companies like the German ones that we have on our mercedes. but if you want the same screw style (no holes in the band) and a wider band/ clamping area, you can use what Saab and Volvo use. Pict below.

I have a good friend that goes to the yard and gets a 100+ pounds of hose clamps that are in factory condition and has them cadmium coated. Its cheap and because he uses a lot of them, nice to have on hand. German style for the fords etc. and Swedish for other cars, depending on what is getting clamped.
