Abstract: A clamping device for fluidically and mechanically connecting two hose barbs. The clamping device includes a seal and a locking mechanism, wherein the locking mechanism can be transferred from a mounting condition to an assembled condition. In the mounting condition, the hose barbs can be inserted into the clamping device, while in the assembled condition, those hose barbs are locked in place in a position in which free ends of the hose barbs face each other and a seal coaxially aligns and fluid-tightly connects the free ends.
