[Closed] Fixing chinese light conector

Hi,

I have had my cheep as chips chinese light for 3 years now, no fires or such like to report. The connector on the head unit (where it attaches to the battery) has started to play up, i gave it a pull last night and its come apart. Is there a way to reasemble these conectors (what tools would I need)

I know easyest solution is to buy another but I have become quite attached to the litte fella.

Cheers
