The one problem I have ran into with these type is the one referred to by that Fleabay link is that they do not have barbs holding the lines on even clamps. I had a lot problems with them coming loose in operation. Now there are versions that have the 1/4 to 5/16 steps with the barbs which work fine.

Here is example of one with the steps and barbs.
