Tonearm lock PLX-500

My tonearm lock just broke!!! Noooo!! I can't imagine... Look at that:

I tried to fix myself, using a super glue. But it didn't work, since the plastic need some "flexibility" for the lock and unlock movement.

Is there any place where I can buy this piece of plastic alone?? I bought this turntable on October/2016, so I suppose that is still under warranty.

Could anyone from Pioneer DJ help me with this problem?

Thank you.
