A flexible tying member for a theftproof device which is adapted to give warning in response to a change in a photo signal transmitted in an optical fiber extending through the flexible tying member. The flexible tying member has a first layer including the optical fiber and at least one electric wire connected to at least one photoelectric element, and a second layer including a reinforcing member. The flexible tying member has a coaxial structure having an inner layer formed by the above first layer, and an outer layer formed by the above second layer, or a parallel structure in which the above first and second layers longitudinally extend parallel with each other.

Flexible tying member for theftproof device

A theftproof device comprising a flexible tying member, an optical fiber extending through the flexible tying member, a light emission element arranged opposite an end of the optical fiber, a light receiving element arranged opposite the other end of the optical fiber, a fixture fixed to an object to be protected from theft, an electrical circuit arranged within the fixture, mechanical connector means for mechanically connecting the flexible tying member to the fixture, and electrical connector means for electrically connecting the light emission element and the light receiving element to the electrical circuit. The electrical circuit is responsive to a change in a photo signal generated by the light emission element and transmitted through the optical fiber, for performing a warning function.
