A quick learner from USA says:
I need 3 of these window lock; no name or number on them!
The latch should have no bump on it; and should be long enough to reach & slides through a horizontal opening built in the fixed part of the window

The lock you show in your photo looks like it was altered or worn down. Compare the measurements to SWISCO part number 90-005 and let us know if you think this could work as a replacement.
