摘要

The consignor has a case fixed on a trolley and a locking mechanism. A key (1) cooperates with a locking mechanism of another trolley and is connected to the case by electric conductors (4, 5). The conductors are connected to an external contact carried by the key at one end and internal contact of the case at another end. The conductors and metallic wires are laid in a flexible plastic sheath to form a deformable flat strip.
