An expansion joint connects structural elements of a building structure to fill a space between the structural elements themselves. The expansion joint has a plate body and a deformable body flanked or adjacent to the plate body along the longitudinal direction. The deformable body includes two superimposed and structurally independent portions connected to each other in a removable way, or configured for a removable connection with one another.
