Zalman CNPS 8700 lost clip?

Just wondering what I should do about this, I bought a zalman cnps8700 from a computer fair, and because it wasn't boxed somewhere between there and home I managed to loose the clip to hold it down.
Now I have emailed Zalman to see if they can supply a replacement clip, but was wondering how I can improvise a method to hold it down on my AM3 mobo if I am not able to acquire a replacement, I am not sure the stock clip would fit as even if it is the correct height and can fit through the heatpipes, it has a lever system to hold it down, and it looks like the zalman is too wide for the lever to lock into place.
