Is there a polarizing feature on this connector? Connectors of this type, with 16 pins generally don't fall out on their own but changing to one with latches would give added security.

How many mating cycles is the connector rated for? It looks like a tin plated type in the photo. One major manufacturer of such connectors, Tyco Electronics, considers 50 cycles a "large number" for their tin plated connectors. This means they will not guarantee "stable electrical contact" after 50 mating cycles.
