A tool, which may have an integral body, serves several functions in installing drip tubes to main drip lines with a coupler. The tool has a needle which punctures holes in the main drip line for insertion of one end of the coupler. The tool has a slotted head which grasps the coupler facilitating the insertion of the coupler into the hole in the main line. Embodiments of the tool may also have apertures in the tool which fit around the coupler for facilitating the insertion of an end of the coupler into the open end of the drip tube.
