Could you post a picture of the housing it came from? It reminds me of a JST or Molex crimp, but it is not quite the one I am thinking.
If you are trying to replace it, then you may have a problem as this will require a special crimp tool to crimp correctly. some people claim that pliers can be used but you will never get a good crimp with those. Soldering can be done, but the crimp then has to be cut down so it fits into the housing
