Abstract

Abstract A pipe connection fitting for connecting a branch pipe to a main pipe has a body with a nipple adapted to enter a branch opening in a main pipe and a bore in communication with the nipple for the connection of a branch conduit to the body. A seal surrounding the nipple for sealing against the pipe is mounted on the body. A pair of opposed ears are integral with the body. A strap has its free ends removably secured to the ears respectively. The strap has a threaded opening midway between the ends thereof with a break-away screw threaded through the threaded opening for engaging the pipe to secure the body to the pipe.
