Getting Replacement Parts for a Thane H2O Mop?

I have a Thane Housewares H2O Mop Steam Cleaner, OEM-TV-001. The secondary model number is: TDC03638-2. This unit was working great until someone was too harsh when removing the water tank in order to fill it. Now, it has a piece broken out of it, leaving the unit non-usable.

I'm attaching some photos to assist finding the correct part.

Thanx for your time.
