Abstract: 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.

Abstract: Disclosed herein is a process for clinching a wire rope on a buckle base, which comprises the following consecutive steps:subjecting a starting anchor block material and the wire rope in combination to a first clinching operation to obtain a preformed anchor block bearing steps therein; andsubjecting the preformed anchor block and the buckle base in combination to a second clinching operation to clinch the resultant anchor block on the buckle base, which second clinching operation is applied in a direction different from the first clinching operation. Owing to the first and second clinching operations carried out in directions different from each other, the resulting stresses are scattered and the anchor block is thus protected from being overstressed.
