Abstract

A sterility separation element can be arranged between plug connectors of a plug connection/electro-mechanical lock to provide sterility separation of the plug connectors. The plug connection/electro-mechanical lock has at least one electrical contact pin that penetrates the sterility separation element such that the sterility separation element fits directly to the electrical contact pin over its entire circumference in a germ-tight manner. The electrical contact pin has two free pin ends configured to come into electro-mechanical or electroconductive plug contact with corresponding electrical plug sockets of at least two lines to be connected.
