A rotatable connector installed in a telephone transmitter and used for connecting a coiled conductor and the transmitter to effectively prevent the coiled conductor from twisting. The connector includes a housing, four conductors for connecting to a microphone and a receiver in the transmitter, four annular guide pieces which can be mounted on a rotation seat and held in the housing and composed of four semicircular piercing guide pieces and four semi-circular guide pieces, a jack for the coiled conductor held in the housing and having several electrically conducting spring strips thereon. The jack can be freely rotated relative to the housing while keeping the spring strips in electric contact with the corresponding annular guide pieces.
