Used these at Americas strongest man for the circus dumbbell and had to adjust / tighten them every time, would much rather use an axle collar

These clips hold on to the bar tight, but they're more expensive than other collars that do as good of a job. These tend do be pretty annoying as they have two screws to tighten as well. I don't find I use mine often.
