If you have hand levers (as in two separate levers not the modern presto type tool) you can remove this in a similar manner to hands, to pry it directly up, you may be able to improvise with screwdrivers otherwise, but that's the method, first time i saw this I thought it had to be pulled apart somehow like other C-clips but no, it pries up and off and is then pressed directly back down again to be refitted.
