Abstract: A pipe connecting seat has a sleeve and two positioning members. The positioning members are disposed on the sleeve at a spaced interval. Each one of the two positioning members has a positioning arm and a positioning pin. The positioning arm is openably, positionably, and pivotally disposed on the sleeve, and has at least one reinforcing protrusion for increasing strength of the positioning arm. The positioning pin is disposed on the positioning arm and is located out of the positioning arm for positioning the positioning arm and limiting a pivoting opening range of the positioning arm. When the pipe connecting seat is connected to two pipes, the two positioning members are always located on the sleeve and are not prone to loss. The operating convenience of the pipe connecting seat is increased.
