The lead comprises a lead section 1, a harness 7 connected to the lead section via a hub 4 and a handle 5. All the components contain electrically conductive elements and form a circuit which when broken leads to an alarm being sounded. The alarm may also be user operated by pressing a button on the handle. The handle may also be provided with batteries which can be recharged by extension and retraction of the lead within the handle. The handle may also have an LED to show the device is active and a radio. In use the lead is used as an anti-theft device and may also have cut-resistant properties. |
