1. A connection unit for connecting fluid lines,
wherein the connection unit has a first connection body which is designed to be connected to a first fluid line not belonging to the connection unit, and a second connection body which is designed to be connected to a second fluid line not belonging to the connection unit,
wherein the first connection body and the second connection body are designed to be connected to one another such that a fluid connection is established between the first fluid line and the second fluid line,
wherein the connection unit comprises a machine-readable code which is not detectable in an unconnected state of the first connection body and the second connection body and which is detectable in a connected state of the first connection body and the second connection body, the machine-readable code being detectable in the connected state from an outer side of the connection unit,
wherein the machine-readable code is arranged on a code element of the connection unit that is separate from the first connection body and the second connection body,
wherein the code element is displaceable relative to the first connection body or the second connection body from a non-detectable position to a detectable position upon a complete engagement of the first connection body with the second connection body, and
wherein the code element comprises a spring device which is designed to displace the code element from the non-detectable position to the detectable position when a force acts on the code element.
