RO Tube Holder

[Aurust]

I'm wondering if anyone knows of a single RO tube holder/clamp that can hold a single 1/4 or 3/8 inch RO tube securely into a tank? I want to add a few extra tubes but don't want to get the tube holders with multiple (4X etc) places for tubes. I want to be able to move between tanks or add a couple extra to a tank.
