A fire-fighting tool for applying a fire-fighting fluid to a fire, comprising:

• an elongate hollow tube;
• fluid input means disposed near to a first end of said elongate hollow tube;
• coupler receiving means disposed near to a second end of said elongate hollow tube, said coupler receiving means further comprising an inner cylinder extending coaxially from said elongate hollow tube, a nub extending transversely from said inner cylinder, and a manually slidable bar disposed longitudinally atop said elongate hollow tube near to said inner cylinder and having a first position towards said second end and a second position away from said second end;
• and
• a hollow coupler tube having a threaded first end and a slotted second end, said slotted second end being L-shaped and having a long leg and a short leg and being sized to engage both said nub and said slidable bar, said coupler tube further being removably attachable to said elongate hollow tube by sliding said coupler tube over said inner cylinder, aligning and engaging said long leg of said slotted second end with said nub, sliding said bar into said second position, rotating said coupler tube to align said bar with said long leg of said slotted second end and aligning said nub with said short leg of said slotted second end, and sliding said bar into said slotted second end in said first position, wherein said bar is disposed within said long leg of said slotted second end.
