## Abstract

The present invention discloses a double-handle faucet, comprising two valve seats, two spools, two inlet pins, two handles, an outlet pipe, a connecting tube, an upper panel, and a lower panel. The double-handle faucet further comprises two semi-cladding members. The two valve seats, the connecting tube, and the two semi-cladding members are all made of a plastic material. Each of the valve seats is provided with an upper annular flange and a lower annular flange. Each of the inlet pins is further provided with a connecting ring. Each of the semi-cladding members comprises two first enveloping parts and a second enveloping part. The two first enveloping parts are located at both sides and correspond to the positions of the valve seats. The second enveloping parts of the two valve seats together cover the outer side of the connecting tube. The two semi-cladding members oppositely cover the outer side of two valve seats to fasten the inlet pin and the valve seats. As compared with the prior art, the present invention not only avoids lead contamination, but also has a low cost.
