A coupling device for detachably connecting a medical device, such as a dental handpiece, which requires at least one operating medium selected from a group consisting of electrical currents, propulsion gas, auxiliary gas, water and light and has a conduit for each of the required mediums, to a supply tube containing feed lines for at least one of the operating mediums characterized by the coupling device including a pair of coupling halves having coacting coupling links, and means for holding the coupling halves in coupling engagement. Each of the coacting coupling links is located in a specific spatial position in accordance with a pattern so that the coupling half attached to the supply tube can be utilized for coupling a different medical device which requires different selected operating mediums.
