A docking seal for the contamination-free connecting of a first flexible casing or enveloping enclosure with a second flexible casing, comprising:
- a first seal device which is connectable or is connected with the first casing, and
- a second seal device which is connectable or is connected with the second casing,
- wherein the first seal device comprises a first docking port, a first end port and a first slider, and
- wherein the second seal device comprises a second docking port, a second end port and a second slider,
- wherein the first slider and the second slider are slidable between a docking position and a throughflow position, wherein in the docking position the first casing within the first seal device-is closed by the latter and the second casing within the second seal device is closed by the latter,
- wherein the first end port and the second end port define a form of the first flexible casing and the second flexible casing by clamping the first flexible casing and the second flexible casing into place,
- wherein the first end port and the second end port serve as an abutment for the first slider and the second slider thereby defining the throughflow position,
- wherein in the docking position, the first slider is in contact on the first docking port and the second slider is in contact on the second docking port,
- wherein the first docking port and the second docking port are detachably connectable with one another,
- wherein the first end port and the second end port are detachably connectable with one another, and
- wherein when the first docking port and the second docking port are connected with one another, the first slider and the second slider during the sliding in the direction toward the throughflow position, in which the first slider is in contact on the first end port and the second slider is in contact on the second end port, the first casing and the second casing open and establish a throughflow channel, encompassed by the first seal device and the second seal device, for the contamination-free transport of a substance between the first casing and the second casing,
- wherein at least one of the docking ports comprises a docking port suspension element.
