Is there a name for this sort of object? I need something like this, but don't know what to type into the webs (lemmy.world)

I'm going to convert my computer chair from pneumatic to static. I'm currently using plastic clasps that are held on with jubilee clips, but they're not great and need replaced (I'm a heavy lad). A sturdy metal version would be better.
