Abstract

A sealing device for sealing a space established by connecting two sealing surfaces (42b, 52b) positioned on one element each of two elements (44b, 48b), for example two concrete pipes, to a position in which the sealing surfaces face each other comprises a sealing body (80) consisting of elastic material. The sealing body (80) is adapted at the connection of the sealing surfaces (42b, 52b) to take a position in the space in which it engages the sealing surfaces. The sealing device comprises an activating device (82-90) for forcing the sealing body (80) positioned in the space against the sealing surfaces (42b, 52b) when the activating device is activated.
