Unknown type of audio interface/connector/cable


Hello, 

I've recently found an Akai HX-M30W stereo double cassette deck and I've been trying to find a way to connect it to a speaker. 
It only comes with a type of connector which I attached a photo of in the link below, I've been searching for the specific name of it in hope of finding a cable for it, but i could not find it.

I hope you can help me! 
Thanks,

While I have never seen that type of connector before, shouldn't the tape deck go through a preamp and not directly to the speakers?
It's really hard to tell what that is in the photo and I am with stereo5 a tape deck would go into a preamp or integrated not a speaker.
