Electrical Connectors

I just an episode of This Old House, The Weston Project. They were in New Hampshire showing how they prefabricated the house. One of the things that caught my attention was the connectors they used to splice Romex wiring together between different wall sections. Does anyone have any info on these connectors and their appropriate use? Do these splices have to be "accessible" like traditional junction boxes, or do they count as a continuous piece of wire?

My guess is that they still would have to be accessible.
