A female tee pipe fitting has a stop only in one of its three openings, the other two coaxial openings which are perpendicular to the first opening have smooth inner surfaces and no stops. When two pipes are to be connected, one of the pipes is severed and a section of pipe removed leaving two free ends. A smooth opening of the female tee pipe fitting is slipped over one free end of the severed pipe and then slid out to slide over the other free end of the severed pipe. After the female tee has been centered, the second pipe is inserted within the opening of the female tee pipe fitting with the stop and the joints sealed.

1. A female pipe fitting adapted to provide a branch for a pipe from which a section of said pipe has been removed leaving first and second free ends of said pipe, said female pipe fitting comprising first, second and third openings, said first and second openings being opposite each other, smooth surfaced and coaxial, the axis of said third opening being at an angle to the axis of said first and second openings, said first opening adapted to fit over said first free end of said pipe so that said first and second openings of said female pipe fitting slide over said first end of said pipe, said second opening of said female pipe fitting adapted to slide over said second end of said pipe, said female pipe fitting being positioned so that the space through said third opening of said female pipe fitting communicates with said first and second openings of said female pipe fitting and said first and second ends of said pipe, said third opening adapted to receive a second pipe to effect said branch from said pipe, and said section of pipe which has been removed being smaller by a predetermined length than the distance between said first and second openings of said female pipe fitting. 2. The female pipe fitting of claim 1 wherein said angle is ninety degrees. 3. The female pipe fitting of claim 1 wherein the inner surface of said third opening has a stop built therein, said stop preventing a second pipe inserted therein from traveling further so as to permit fluid traveling between said first and second openings to enter said third opening. 4. The female pipe fitting of claim 3 wherein said first and second openings of said female pipe fitting have substantially the same inner diameter. 5. The female pipe fitting of claim 4 wherein said third opening of said female pipe fitting has substantially the same inner diameter as said first and second openings. 6. Apparatus for interconnecting a plurality of pipes, a first one of said pipes having a first end, a second one of said pipes having a second end, and a third one of said pipes having a third end said apparatus comprising, first and second coaxial openings, said first and second openings being opposite to each other, each of said first and second openings being circular in section and having a smooth inner surface, a third opening, said third opening having a circular cross section, said third opening being formed so that fluid can flow between said first, second and third openings, the axis of said third opening being at an angle with the axis of said first and second openings, said first opening of said apparatus adapted to be slipped over said first end of said first pipe, and then said second opening of said apparatus adapted to slip first over said first end of said first pipe and then over said second end of said second pipe, the distance between said first end of said first pipe and said second end of said second pipe being smaller by a predetermined length than the distance between said first and second coaxial openings. 7. The apparatus of claim 6 wherein said third opening has at least one detent on the inner surface thereof to prevent said first end of said second pipe from occluding the passage of fluid between said first and second openings of said apparatus and said third opening of said apparatus. 8. The apparatus of claim 7 wherein said angle is ninety degrees. 9. The apparatus of claim 8 wherein said first and second openings have substantially the same diameters. 10. The apparatus of claim 9 wherein said third opening has substantially the same diameter as said first and second openings.
