Place a clamp at the second end of the tube, extend or match when inserting or matching into the coupling, then tighten or match.To fix the leak, use a hacksaw. There is a section of line that is leaking. Place a lock on one of the ends and tighten it. If you want to insert the nipple into the pipe, you have to tighten the clamps on the second pipe end.
