Looking for a plugin “link back html”.

Hi!
Im looking for a plugin such as this one:
http://www.seo.se/blogg/?m=200603

As you can se this guy have a short description saying “
Om ni fann detta inlägg användbart och vill länka till den.
Kopiera koden nedan och klistra in den på er hemsida (Ctrl+C to copy)
Den kommer att se ut så här: Sökoptimering tips”

meaning:

“If you found this useful and wants to link to this post, just copy/paste the code below. It will look like this: “Sökmotoroptimering tips”.

I want to make it easy to link to my post, and I want to provide the permalink in a box just like he does.

Whats the name of this plugin?

Thanx / googoodoll
