An apparatus for introducing air and/or sealant into a tire includes a container for the sealant which has an inlet and an outlet and a pressure generating means, wherein the inlet of the container is connectable to the pressure generating means and the outlet of the container (14) is connected or connectable to the inlet end (24) of a hose (20) whose outlet end is connectable to the tire to be filled. A latchable coupling is provided for connecting the pressure generation means to the inlet of the container, with two latching levers (50) provided at the container (14) being designed to release the locking convection of the coupling on a movement of the respective free lever ends toward one another.
