The clips are probably for expansion and contraction as glass expands due to temperature change. I learned this recently, as I work in a brand new build Tim Hortons, and I being nosey and stuff asked the glass guys as they were finishing the exterior what was the deal with the clamps holding the glass in. They are temporary as I couldn't understand why the guy was removing them when they put the molding on the outside.
