<p>The detector (1) has two pressure detector parts (4, 4') comprising indicator elements provided with an attack surface. A coupling element (9) couples the detector parts in a state, such that the detector parts are associated with each other, when the traction force exerted on a pull medium i.e. link chain, does not exceed a predetermined tensile force. The coupling element couples the detector parts in another state, when the traction force exceeds the predetermined tensile force, such that halves of the indicator elements are arranged outside housing parts (3, 3').</p> |
