A locking cable for use in an antitheft device adapted to give warning in response to a change in a photo signal transmitted through an optical fiber longitudinally extending through the locking cable. The locking cable comprises a core portion including the optical fiber, a reinforcing layer concentrically disposed around the core portion and including at least one electric conductor and a plurality of reinforcing members, and a flexible hollow protective member as an outermost layer covering the electric conductor and reinforcing members in contact with the protective member. If required, a further reinforcing layer may be interposed between the core portion and the first-mentioned reinforcing member, which includes a plurality of second reinforcing members. A holder holding an end of the optical fiber and a photoelectric element in face-to-face relation to each other is axially movably arranged within a plug connected to an end of the locking cable. Space is defined between the plug and the holder, through which the electric conductor axially movably extends.
