Claim:
1. A coupling device comprising: a first coupling element connectable with a hose assembly, a second coupling element for at least one coolant line, wherein the second coupling element is embodied as a socket, is integrated in the first coupling element, and has at least one undercut, the coupling and decoupling direction of the second coupling element being orientated transverse to the longitudinal axis of the first coupling element or to a longitudinal axis of the hose assembly when the first coupling element is connected to the hose assembly, and a plug element coupled to the second coupling element in that the at least one undercut of the second coupling element is connected in a positive-locking, mechanical way with the plug element, the plug element being embodied block-like and comprising a first hollow-cylindrical pin element embodied for the gas and fluid proof transmission of a cooling medium to the second coupling element, the plug element further comprising a second hollow-cylindrical pin element, the first hollow-cylindrical pin element being allocated for a feed coolant line for the cooling medium, and the second hollow-cylindrical pin element being allocated for a return coolant line for the cooling medium, the plug element further having a first connection piece for a feed line of a coolant line and having a second connection piece for a return line of the coolant line for the cooling medium, the first and second connection pieces extending transversely to the first and second hollow-cylindrical pin elements, the plug element having a connection interface and being embodied symmetrically with respect to the connection interface, the connection interface being able to be coupled with the socket in two orientations differing in 180°, wherein the first and second coupling elements can each be coupled and decoupled independently from each other, and wherein the socket is a plug connection.
