Hi, you don't mention your coach or year but posting a picture of your latch may help others provide some specific feedback. You could try some RV window suppliers to see if they sell the same window latches. Don't rush to glue your latches especially if they were not glued originally.....there is probably a reason they came loose (crack perhaps) and a replacement part may be a better solution for you....especially if future replacement is required again.
