Lowpro
Thats what I did occasionally, when no clip was available, but then I had a wire break off the plug once, took an hour of futzing around to fix it, not worth the time lost. Another customer bent the pins trying to force it back on the wrong way. Also had my dad break the display by squeezing so hard to get the back off! Forgot to drill the hole, dumb, dumb. Never had anyone screw up the paper clip trick, though, but there's still hope !
