Abstract: The invention relates to a data link between a first computer (1) and a second computer (2) for transmitting data. The aim of the invention is to provide a data link which is configured in such a way that non authorized third parties are not able to influence said data transmission or to find their way from the outside to one of the computers and to tamper with data. The inventive data link comprises a lock element (6), a first lock gate (7) being placed between said first computer (1) and said lock element (6) and a second lock gate (8) being placed between said second computer (2) and said lock element (6). The first lock gate (7) is closed when the second one (8) is opened and vice-versa.
