Every once in a while I need to put a rack mount switch on a table for a few days for LAN access. Does any company make a locking enclosure for a single 1U switch? The smaller the better. Just something that will keep people from bumping fiber connections and messing with RJ45 connections.

Closest thing I can think of is something like this 10U wall-mount rack. (Np affiliation, I just buy some stuff from them occasionally.) For this one, you'd have to bolt on some sort of back cover, but that could just be a piece of wood.
Try googling variations of "wall-mount 19 rack" or "desktop 19 rack"
Also try searching for "enclosures" not racks, that's how I found this one:

One last result that turned up searching for desktop 19" enclosures. Never heard of this company before, but this looks like what you're after:

Not endorsing any of these products or the supply company in particular, but it's a good reference for what is available: http://milestek.com/c-1451-small-system-wall-cabinets.aspx
Such cabinets are extremely common. Where to get one will depend on just where you are, as it's unlikely to be cost effective to have them transported any great distance. I suggest you pop in to your local electrical wholesaler (or whatever they're called where you are) and pick the one you like from the many available makes and models.
What about Fly cases ?
You can get a small one like this one : http://www.woodbrass.com/flight+case+rack+4u+gator+gr4l ,
Close the front door to hide the switch, and pass the fibers and cables by the back.
It's standard 19" so it should not be a problem, I use this for my lab.
