In one of the rooms I run there are a number of extension cords that
stay coiled by the outlets. Every couple months somebody "borrows"
one. Does anyone make a clasp of sorts that would fix the plug to the
outlet and help to deter people from helping themselves?

Yes, but I'm not sure who. It's basically a zigzag shaped piece of
steel about a quarter inch wide that screws to the center screw of the
outlet and hangs over the plug. For this to work, the plug has to be
one of those 90 degree models.

I used to use these in studios where the main power was taken from a
wall outlet that was exposed to kicking the plug out by accident. I
think I got them at the local hardware store, but it's been a decade or
so...
