Hose clamps

[trilinearmipmap]

What can I use to clamp hoses in place when I'm siphoning, filling a bucket with RO water, etc. I've had too many accidents with hoses flipping out of place and siphoning water onto my floor.

I need some kind of clamp to hold the small flexible RO tubing onto the bucket rim. Also a larger type of hose clamp to hold the flexible 3/4" hose onto the aquarium rim when I'm siphoning out water.
