Child lock for greenhouse

Supercell

With two kids under 4 and another on the way I'd like to put a lock on my greenhouse. The floor is pebble dash which seems to be a magnet for little people. Besides that I have all kinds of stuff lower down (slug bait, tomato food etc) that would be better kept away from little hands and mouths.

The greenhouse is bog standard aluminium frame with poly plastic windows. The lock doesn't have to be very strong , just has to be enough to dissuade little people.
I've had a quick google but didn't find anything.

Has anyone any suggestions or links? Thanks.

Would a simple catch not do the job?

As suggested, one of these http://www.ebay.com/itm/Marine-Boat-Door-Hook-3-in-Chrome-Plated-Brass-Cabin-Hardware-Seachoice-36141-C-/301593789869 would do the job, available very cheaply from any hardware shop. If you use a very thin bit (finer than the screws) you can carefully drill into the aluminium frame to make a starter hole and it will be easy to insert the screws (use very short screws).
