Reply to Usb Damage?

Hey DJTTF.
I was just plugging out my s4 when suddenly.. Pow! The little orange thing from the usb plug in the kontrol s4 just flew of and now i can't find the orange thing again. My controller has been harsh to plug in from the start so is it the point to take this orange thing off? And if not and if i find it can i put it back in?
