Need help with coming up with a search term... I turn to you, DIY.

I am building a custom scooter and working on molding a housing for the electronics. It is a two piece job that is essentially a box, cut in half, that I want to mate together using "a piece of hardware" molded into the fiberglass. I say piece of hardware because I am a total loss as to what to look for... or what to call it.

Here is how I can best describe what i am looking for. A two piece "coupler", one piece of which I can permanently attach within the electronics compartment. The other I would graft into my custom box. These two pieces would mate and make a strong enough connection to take road vibration. On the exterior face I would require some sort of latch, button, pin, twist, lock... something to open/close it.

Here is a little animated gif of the action I am looking for: Whatchamacallit

What is it that I am looking for? What would you call it? And can you think of any trick little latches like this available out there?

Thanks much.

edit: Something like the interface on this compression lock: Ebay, but that also functions as an anchor... there would be no hinge to rely on to keep the piece in place using a simple lock... it has... I don't know, couple?

ONE MORE EDIT: Thanks everyone for the help, this has helped me whittle down what I am trying to find. The main issue I have with most of the ideas posted is that the cam locks and other latches simply close a door. They rely on a hinge to hold the "door" in place. I won't have that. I need this device to securely hold the piece in place, not just provide opposing pressure. Does that make sense?
