Question about Samsung Swa-8500s

Hi, can you please help me. I have the Samsung SWA-6000 and one of the cables for the surroundspeakers is broken. What are those specifically called, and where can you get spare ones to replace with? When I search, I keep finding rolls of speaker wires, but I need one that is split on the end that goes into the speaker itself, and have the plastic plug, fitting into the wireless box in the other end. Thank you.
