The invention relates to a sealing device ( 1 ) for sealing off a joint ( 4 ) between a first and a second structural body ( 5, 6 ), in particular between concrete bodies, in the region of the joint ( 4 ) an injection duct ( 3 ) being provided, which is filled or can be filled with a sealing medium in order to seal off the joint ( 4 ) and/or voids ( 4 a, 4 b) present in the region of the joint ( 4 ), the injection duct ( 3 ) having arranged in it an extruded spacer body filling the injection duct ( 3 ), and the injection duct ( 3 ) being formed solely by walls of the structural bodies ( 5, 6 ), the extruded spacer body being a hollow profile extrusion ( 2 ) which has inside it at least one hollow profile duct preferably continuous in the longitudinal direction and a three-dimensional shape which withstands the hydrostatic pressure of the wet concrete during the pouring of the second structural body and can be pressed in when sealing medium is pressed into the injection duct ( 3 ) and which narrows the cross section and is set back from the walls of the injection duct ( 3 ), preferably as far as the joint region. The region relates, furthermore, to a hollow profile extrusion for a sealing device and also to the sealing-off method.
