Not HJ. It's the design of the buckle of the Freiwillige Schutzstaffel, the Volkdeutsche in Slovakia. There is a version for officer (round), like this it is a fantasy buckle from eastern countries.
Looks like someone tried to incorporate as many devices as possible to reach a greater market. You've got HJ, Reichsnährstand, RAD (albeit 180 degrees out), SS and the NSDAP all in one buckle
