1. A hose coupling for a fluidic connection in an analytical system, comprising:
a sleeve comprising a first hollow cylinder, a channel of which is connected at one end to a hose and the other end of which comprises a first opening for receiving a plug, the end for receiving the plug being at least partially surrounded by a locking ring with a recess, the first opening of the sleeve for receiving the plug extending at one side into a second opening which continues as a channel extending along a radius of the first hollow cylinder, wherein a flange having a face is disposed between an end of the hose and an inside of the first hollow cylinder of the sleeve; and
the plug having a base plate from which extends a second hollow cylinder which has a hook arranged at an end opposite the base plate and extending radially outwardly, the second hollow cylinder being configured such that the second hollow cylinder is at least partially insertable into the first opening of the sleeve and the hook is configured such that the hook can be inserted completely into the second opening of the sleeve and, during a rotational movement, the hook engages behind the locking ring of the sleeve to secure the plug against linear movement, the base plate of the plug having a projection with an edge which, during a rotational movement, engages in the recess of the locking ring of the sleeve to secure the plug against rotation.
