What is this on an '04 Accent Engine?
 

So, can you tell us why you want to know what that part is, or is this just a set-up for somebody selling us spam?

I would like to know because I broke the plastic clips, both male and female sides, while trying to remove my O2 sensor. I'm using electrical tape to hold everything together for now. Any info on this component would be great. And no, I'm not looking to spam anyone like the first reply. Thanks for your help.

You can glue the sensor side with some superglue or airplane glue, then attach the female end with some silicone. I do stuff like that all the time myself.
