Vent window locks can serve several purposes. Originally they were designed to help prevent break-ins from occuring. In the 70's manufacturers (like Volvo) started glueing the latch to the window for a cleaner appearance. Unfortunately the glue eventually fails and the latch mechanism falls off.
Whatever your need is, these supplemental latches will assist in keeping your vent windows locked.
