These handy little fasteners can be found on many removable panels where "relatively easy" access is required. They require a tool like a screwdriver or a coin to open them.
These are found on many RV's, trailers and motorhomes (on the exterior refrigerator access panel).
Made of white Nylon, these latches are inexpensive, but very durable, especially in environments with high levels of humidity.
