Abstract: A pipe saddle assembly is disclosed herein and includes an outlet body arrangement, preferably of the cartridge insert type, which is adapted for positioning adjacent to and around an opening in the wall of a pipe. This insert-type outlet arrangement, which includes means to insure that a uniform seal is provided against the pipe wall around the opening, is connected with at least two lugs also comprising part of the saddle assembly. These lugs are located on opposite sides of the boss arrangement, one of the lugs in one embodiment preferably being positioned substantially closer to the outlet arrangement than the other lug. In addition, each of the lugs preferably includes a slotted opening on one side thereof. The saddle assembly also includes a curved strap adapted to extend around a portion of the pipe and including opposite ends preferably adapted to be disposed in the slotted openings for interlocking engagement with the lugs.
