How can I replace the fan connector lid?

I recently opened up the MBP last week, and accidentally broke the fan connector lid of the logic board that keeps the fan wire intact. It’s the small lid at the end. It’s not there and I cannot find it anywhere. The MBP works well meanwhile, but however starting yesterday the fans are suddenly stopping at the mid of a heavy task, and after a few minutes start at high speed. I am sure it’s due to the loose connection.

Is it possible I can get a replacement part or should I finally take the laptop to the service?
