An extensible and self-retractable cable device is provided comprising, in one embodiment, a casing having winding cable, two reels, two spring housings, and two springs mounted within the casing. The device enables the manual withdrawal and automatic re-entry of a telephone cord connecting the handset to the base of a telephone set, thus, preventing the telephone cord from becoming crinkled and coiled up in an objectionable manner.
