A self-tapping tee for heavy walled plastic pipe such as polyvinyl chloride (PVC) or thick walled polyethylene tubing. The self-tapping tee includes a saddle for gripping a tubular line to be tapped, a coupling tap with a stem for poking a hole in a sidewall of the line, with the sidewall of the line around the hole stretched about the stem, forming a seal, and a removable mandrel for supporting the stem while the hole is being made.

1. A saddle for a tubular line, said saddle formed of two substantially identical sections, each section comprising one-half of a cylindrical housing mounted on one-half of a cylindrical clamp, each one-half of the cylindrical housing having a female latch member on one side of the parting line between the halves, said female latch member having a pair of spaced sidewalls, and a male latch member on the other side, said male latch member having a resilient tongue and a head designed to latch between the spaced sidewalls of the female latch member, and each one-half of the cylindrical clamp, at the bottom parting line between the halves, having a portion with a radially, outwardly extending rib and a portion with a second radially, outwardly extending rib with a tree end hooked over to form a groove for receipt of the first rib of the other section, whereby said sections are assembled first by sliding interaction of said first rib in the groove of the second rib of the other section at the bottom parting line of the cylindrical clamp about the tubular line and thereafter latching interaction of the male latching member in the female latching member of the other section at the parting line between of the cylindrical housing to fixedly secure the saddle about the tubular line.
