    • PURPOSE: To prevent leakage in connecting a lateral pipe to a main pipe by forming a continuous passage in the axial direction of a saddle tee assembly coaxial to the lateral pipe, a clamping device applying tension to a collar and forcing the collar against the main pipe. CONSTITUTION: The saddle tee assembly is composed of a saddle tee boot 52, a collar means 55 and a clamping device 56. the saddle tee boot 52 has a flexible saddle 53 and a cylindrical hollow tee 54. The saddle 53 attaches to the main pipe 50, the hollow tee section 54 receiving the lateral pipe 51. The flexible collar 55 overlies the saddle 53 about the periphery of the hollow tee 54. The clamping device circumscribes the main pipe 50 to apply tension along the circumference of the main pipe to the collar 55, thereby to force the collar 55 into the saddle 53 and the saddle 53 against the main pipe 50. Thus, the saddle tee assembly has a universal application and is particularly suitable for leakage prevention in connecting a lateral pipe to a main pipe.
