         5 . Coupling device according to  claim 2 ,
 wherein the coupling device is formed in such a way that the adapter piece can only be arranged therein with predetermined orientations, in particular via a corresponding profile of at least one of the receiving openings.   
     
     
         6 . Coupling device according to  claim 2 ,
 wherein the elongated hollow bodies further comprise a predetermined cross-sectional profile and the adapter piece comprises a correspondingly profiled receiving area for receiving the hollow body.   
     
     
         7 . Coupling device according to  claim 1 ,
 further comprising at least one clamping device, which is formed to clamp at least one of the hollow bodies and/or the adapter piece fixedly in the coupling device.   
     
     
         8 . Coupling device according to  claim 7 ,
 wherein the clamping device is arranged in the area of one of the receiving openings or wherein the clamping device is arranged in the connecting channel of the basic body and for example further comprises a pressure element, which can be brought into contact with the hollow body and/or the adapter piece with the production of clamping forces.   
     
     
         9 . Coupling device according to  claim 1 ,
 further comprising a connection area for the supply of a pressure medium, for example in the form of a compressed air connection, wherein the connection area is connectable in a fluid-conducting manner to at least one of the hollow bodies.   
     
     
         10 . Coupling device according to  claim 9 ,
 further comprising an adapter intermediate piece, which can be arranged in the coupling device in such a way that at least one of the hollow bodies is connectable in a fluid-conducting manner via the adapter intermediate piece to the connection area.   
     
     
         11 . Assembly, comprising a coupling device according to  claim 2  and at least one further exchangeable adapter piece, wherein the adapter pieces are formed to receive hollow bodies with cross-sectional dimensions different from one another. 
     
     
         12 . Assembly system,
 comprising at least one coupling device according to  claim 1  and two elongated hollow bodies, which are connectable to the coupling device, wherein the elongated hollow bodies are formed as supply hoses for assembly elements for a tool unit.   
     
     
         13 . Assembly system according to  claim 12 ,
 wherein the assembly elements comprise connecting elements and in particular rivets and wherein the assembly system is formed, for example, to undertake the supply of the assembly elements to the tool unit with a compressed air impact on the supply hoses.   
     
     
         14 . Assembly system according to  claim 12 ,
 comprising an industrial robot with a plurality of moving robot limbs, wherein the coupling device is arranged on one of the robot limbs and, for example,   wherein the robot limbs form a kinematic chain, at the end of which a connection area is arranged for the tool unit, and the coupling device is mounted on a robot limb, which is spaced by a maximum of four robot limbs from the connection area.
