Now this is my opinion and not fact, I'm of the belief the heel hook well predates Sambo. There are heel hooks in traditional Japanese Jujutsu as well, however they manner of application and positon of control is extremely different that wouldn't resemble anything that you would see in a grappling match/mma fight today. Most Katame-waza/ Ne-waza in Jujutsu was when one person was standing over the other.
