A sealing device for sealing two concrete pipe end portions in relation to each other comprises a sealing surface (4) in a socket (2) of one of the pipe end portions and a sealing surface (14) on a spigot end (12) of the other pipe end portion. The spigot end is introduced into the socket and there is between the sealing surfaces formed a sealing space in which an elastic material sealing element (26) is positioned in a compressed state. A closure device (28) is positioned in the sealing space between the interior of the pipe end portions and the sealing element (26) for preventing a medium conveyed in the pipe end portions from contacting the sealing element as well as the sealing surfaces at least in a region of the sealing element.
