I purchased this a few weeks ago:

Pet Lookout Car Booster Seat - Automobile Travel Gear - Pet Travel Gear

However, despite following what little directions it came with, I had a bad experience with it. Roxie tried to get out of it while I was driving and wound up hanging out the side by her neck! I had to pull over quickly in order to fix the situation. Needless to say, I returned it.

I use this and it works just fine. I can also use it for walks.

Amazon.com: Easy Rider Car Extra Small Harness for Dogs, Black: Kitchen & Dining

Mine have occasionally climbed out, but since they wear a harness it doesn't harm them. The tethers are long enough that if they do they reach the actual seat and just kinda stand there until I stop or if not driving, reach back, and tuck them back up into the seat. I would not have thought to attach a tether to a collar on their necks. I only use their collars for their tags, never for attaching a leash or tether or anything like that. I only use harnesses for those things.
