ABSTRACT:
A saddle and tap for lawn and similar irrigation systems. The saddle includes a base portion that snaps on the delivery pipe of the system and a pair of threaded, upright portions that extend upwardly from it. The tap includes a piercing member, barrel section, and threaded annular nut. In operation, the barrel section helps to guide the threaded upright portions of the saddle into the threaded annular nut of the tap. Rotation of the nut then advances the piercing member into the pipe. The tap is releasably lockable on the saddle and the piercing member of the tap is provided with holes with radiused or rounded edges to prevent creating undesirable shavings as the tap is advanced through the pipe wall.
