Como se dice "hinge"

For some reason, the door to my room fell off the only hinge it was on. I understand that the wind is howling outside and all, but this door is an inside hall room door. After I shoved the almost balsa wood door back into and onto the door frame,  the door became only slightly loose and proceeded to bang obnoxiously as the wind rhythmically sucked its way through the house. And it's like 3am on a Sunday night.
