PROBLEM TO BE SOLVED: To provide a joint with test connection reducing the weight of a test connection part, and resistant to vibration due to traveling of an air brake-mounted vehicle.SOLUTION: A joint 1 with test connection includes a test connection part 200, and a joint part 100 for a resin-based air brake pipeline having a cylindrical part 110 to which the test connection part 200 is press-fitted and attached. The test connection part 200 includes a metal cap material 210, an air discharge hole, a valve body 220, a valve spring 230, and a packing material 240. In a connection state of equipment for pressure test to the test connection part 200, air in an air flow passage of the joint part 100 is guided to the equipment for pressure test.SELECTED DRAWING: Figure 1
