Hi everyone...Does anyone know of an online source for those little black latches that come on the TIF scales and Yellow Jacket leak detector blow mold cases?

Most of mine appear to be the same size across different cases, and most of them are missing (snapped off) the little tab in the center that actually holds the latch closed. I was going up a ladder today carrying my scale and the case opened up and the scale tumbled to the floor. Not good.

If I can't replace them, I will have to figure out some other way to firmly close several of my cases.
