A few years ago there were worm drive clamps available that had
rolled edges to avoid cutting into the hose.
Those are no longer used or available.
The current style of efi clamps have a small bolt & nut thru them
and are a solid overlapping band.
That's what I used when I installed my external fuel filter and
the brass quick disconnects.
They're available at any regular auto parts.
Just be sure to get small enuf ones that clamp tight on
the fuel lines, and that don't come to the end of their
travel (smallest possible size fully closed) without
tightly clamping the line or hose.
You can see a picture of them here

If you get to the point you want to do the external filter thing,
it's much easier just to use a short piece of the right size of
hard copper tubing to replace just the filter instead of that big
loop of hose that's a little hard to tuck up into the tank without
kinking it. Not too long ago someone posted about that and
included a picture and I think the tubing size. You could find
with a search.
I think if I did that I'd use a long enuf piece so that I could
2 clamps on each end just for a little insurance. It's 5/16 efi hose.
And be sure to have a new big O ring if you do the external
filter thing. Part # 16 14 1 341 006. And be very very careful
not to tighten the small nuts that hold the fuel pump mounting
plate into the side of the tank, they reportedly twist off very easily.
Might not hurt to put a dab of blue loctite on them.
Cover everything under those QD's really well, several layers deep,
when you take them apart so you don't leak any gas down onto the
motor or trans. It's impossible to get the yellow stain off.
