The HF ones are OK, but they don't make them in 1/4" drive- I assume because of the design. I have the HF in 3/8, and they work ok, but I can pull a socket off of them without much difficulty. While this is probably acceptable, I have the SK in 1/4 and 3/8 and can't pull a socket off of them within reason; it's a far superior design. So, if you want locking extensions in 1/4, then this style might be your only choice. And if you actually want very secure retention, this style is better over the ball retention method that's also used on QR ratchets.

Locking extensions

What do you mean? You use the set screw to lock it onto a normal extension and then you use the collar to lock and release a socket.
Why did you buy it if you don’t know what to use it for?
what are the practical purposes?

I never had a use for locking extensions. My Snap-on extensions and sockets snap together tight.

I have a couple of Facom 3/8 drive locking extensions, they definitely help working with rusty hardware and awkward to reach spots where you don't want to leave a socket stuck on a bolt head or worse dropping into the "mysterious 10mm socket oblivion" never to be seen again!!!
