A coupling device of a transport cart, through which the transport cart can be coupled to a structure of a supply panel for medical applications, wherein the supply panel can be positioned through a ceiling mount. The coupling device has a first and a second jaw that can be coupled to the structure of the supply panel, wherein, in order to couple the transport cart to the structure, the first jaw, via a first latching device, and the second jaw, via a second latching device, can be locked into a closed position (FIG. 6) from a stopped, uncoupled open position upon mechanical pressure contact with the structure.
