Here the power company makes those connections and they use crimp connections with a plastic covering over the crimped area.
When we temp the connection we use the cheapest split bolts we can find because the power company will just cut them off and use their crimps.

Like Dennis mentioned there is snap on plastic covers for those connectors.
If you want shrink, heat shrink is less costly than cold shrink though cold shrink typically has better UV resistance I believe.
Over here in NJ most of the time they do not cut and re-splice anymore. I dont usually use the plastic covers because they crack or don't stay connected so generally tape is put over. Had a few call backs because when it starts to let go people call because they see the flag or flap and think there's a problem. This is why is usually use the rubber coated polaris connectors.

Bet those same people call if the nylon jacket on THWN starts to come off as well, which I have seen happen many times.

If I'm making a temp connection, I use set-screw butt splices, then tape them. POCO replaces them sometimes
You can also buy them with plastic caps. That makes them underground splice kits

When I was a helper, the boss had us use Tomic connectors as temporary splices.

Shrink tube caps is about only thing worth using for underground splicing.If I'm making a temp connection, I use set-screw butt splices, then tape them. POCO replaces them sometimes

This is what I use. These are super cheap and I think there are five different sizes which cover pretty much any size. I believe they make a clamshell for them too.

Clamshells is one name, I had one old timer who called them pocketbooks.

Don't think there is any specific term used across all the brands other than may just call them a cover in the catalog. Some may specify "direct burial rated" if that applies.
