Vinyl window replacement locks

[sarmistead]

I have no-name vinyl windows in my home, mostly in good repair. However, there are a couple with missing or broken locks, which I'd like to replace. No luck finding replacements, yet, so am seeking your help. The locks I'm seeking mount into the window track, allowing the window to raise and lower the full length of the run. When the locks are opened (or set), they prevents the window from opening more than about 2 inches - nice for ventilation while still retaining some degree of security.

Can anyone point me to a vendor that carries replacement locks that resemble these pictures:
