A separable faucet mainly provides two control bodies, an outlet assembly, and a three-way pipe assembly. A control valve is disposed in each control body, and connected to an inlet pipe and an outlet pipe. One end of a plastic inner pipe of the outlet assembly is connected to a spout piece, and an outer edge is covered by a metal cover to counteract changes in water pressure by the metal cover to ensure a tight combination between the plastic inner pipe and the spout piece. Another end is connected to a connecting pipe, and an outer edge is covered by a metal cap secured to the connecting pipe to urge the plastic inner pipe against the connecting pipe tightly by a minor diameter part of the metal cap. The three-way pipe assembly is connected to the connecting pipe and outlet pipes of the two control bodies respectively.
