new pane in aluminum window

I am replacing a pane of glass in an aluminum window. Once I get all of the old (and I do mean OLD) glazing compound out, what should I use to secure the glass in the window. Of course, I know I will use glazing compound, but I can't use glazier points because the window frame is aluminum. In removing the broken pane, I found two pieces of wire that had been twisted and embedded in the glazing compound. Was this a "home made" remedy when the house was built or the windows were manufactured? Are such pieces available somewhere? If so, what the heck are they called?!

 

The wire you found is actually a glazing clip used to hold the glass mechanically. What you can do is clean all the old glazing compound...apply a bead of silicone....press the glass against the silicone and apply glazing compound. The silicone will hold the glass in the aluminum frame just as the old clip did.

 

Thanks for the tip. Very helpful.
