go to the local hard ware store. It will be a brass fitting with multi level looking things. One end should be about an inch of that and the other should be fairly small with a small nut to pinch the tube between the nut and fititng body.

This is from a buddy of mine
"pcv isnt needed. its for emissions. its supposed to go into the intake to cut down on pollution and what not. you can just take the hose off or get valve covers with breathers and do away with it. dont plug it off, the engin has to be able to vent out gasses made inside by movement of parts, heating up, cooling down and what not"

u shouldnt leave it disconnected. the gases in the case are byproducts from combustion in the cylinders that force their way past the piston rings and will form damaging sludge in your engine

What engine is this? You want the hose attachment point to seal up or you'll get unmetered air into the engine. I'd try and get the attachment point about the same as it was stock...ie... if it was before the throttle body before keep it there, if it was after the TB keep it there. My 5VZFE has one before (drivers side vent) and one after the TB (Passinger side vent). And no its not just for emissions, did you read that link I gave you? Here is it again in case you missed it:

Heres a quote from it:
I'm thinking (could be wrong of course) the reason my V6 has one PCV hose in front of the TB and one after the TB is to setup a pressure gradient between the 2 vent hoses and increase flow. But I'm open to other ideas on why the Toyota engineers did that. I'm a believer in keeping things stock if you don't understand why the engineers did what they did.

Heres a quote from it:
The actual cause of the problem is an inability of the engine's crankcase ventilation system (PCV) to move the normal gases from the engine. When these gases stay longer in an hot engine it allows deposits to form on the metal parts of the engine. When enough deposits are present "Sludge" is formed. In my opinion the reduced flow of the PCV is related to the vehicle emissions. This presents a problem since to correct it may require Toyota to recertify the engines, come up with a solution acceptable to the EPA and then they still have to repair or assist in repairing the affected engines. The costs would be staggering but ignoring the problem, in so many of their best selling vehicles, may be worse in the long run. In the various articles I've listed below, if you want, you will learn more about the cause an effect.

As i mentioned...look in my signature. Its a buick 3.8L carbd..not fuel injected. The hose was run from the valve cover and into the aircleaner VIA a hole in the bottom of the aircleaner. It was like that when I got the truck from the PO.

Note to self: stop typing after
After looking at your pic closer, I'd say look at drilling (and taping if its thick enough) that shiny air filter bracket thingy and screw a hose barb fitting into it. If you use a nut to hold the fitting in place be very carefull it doesn't come off and get sucked into the engine (very bad). Since it uses a carb you don't have to worry about unmetered air getting in, but you still should worry about unfiltered air getting past the air cleaner and use some sealer around the fitting threads.
Was there not a vent for the other valve cover on the other side?

On my 22r, there are two places on the intake. One is the PCV and runs into the intake, leave that one if possible. The other one runs from the VC to the top of the air filter. That one you can just put a small cartridge filter on and call it good.
The difference is the PCV will have a valve that sits in a rubber grommet on the VC, the other one will just connect with no valve.
