window parts

[Bob]

I have a couple replacement windows that don't stay open because the plastic pins that hook in to the sides are broken.

Can some please answer the below questions I have.

1. What is the official name for this piece? That way I can search for it.
2. Are there any good places online to find these?
3. Are they different for every window brand? How do I find out who makes my windows? I don't see any labels anywhere.
4. Any other information that would help me to replace these pins.

Thanks in advanced.

You wouldn't have 'California Window' windows do you? If you do, good luck...
