Abstract
A threadless coupler for connecting two large pipes in line and a third, relatively small pipe to form a Tee. The coupler has a clamp for engaging a male groove formed in each large pipe, the small pipe being connected by threading. The clamp comprises a collar surrounding the retained pipe. The clamp connects to the coupler by threaded fasteners. The coupler has two internal elastic seals which close over their respective large pipes. The clamp may be an annular collar which must be slipped over a pipe prior to forming the male groove, or two complementing sections which may be placed over the pipe after forming the groove. The coupler and pipes are all fabricated from non-malleable materials.
