Clip to retain sash cord

Question

The picture is of the clip holding the sash cord at the top left of the window as viewed from the inside. The sash cord is attached to the block and tackle balance assembly at the bottom. It looks like most of the balance assemblies I saw on here are actually screwed in but mine hang from the top of the window using that clip. About 80% of those clips have broken in my house therefore the windows will not stay up because the cord can't be attached to the broken tip. If I could find these clips and figure out how to remove the broken ones (I think they are hooked through a hole in the jamb), all my windows would be fixed. The balance assemblies seem to be fine. Is there a name for these clips and can I buy them? The window locks have "MW" stamped on them. I don't know if these are M&W windows or something else. Any guidance would be appreciated.

Sure, we can definitely help. This old nylon piece is a hook that goes into a hole at the top. I'm afraid they're no longer made, and the balances you have are designed with metal screw tabs. We actually sell a screw plug, our 26-200, which fits into the same hole where the old nylon hook went. If you pop the 26-200 in that hole, you can install the modern style balances with the metal screw tabs.
