Abstract: A structural joint is sealed with the aid of an injection hose including a substantially liquid-impermeable base body which envelops a passage channel and which has exit openings distributed over the length of the base body for passage of injection liquid from the passage channel into the joint to be sealed. The exit openings open under internal excess pressure and I close under internal negative pressure. Following injection of the injection liquid into the joint to be sealed, the injection liquid remaining in the injection hose is drawn off from the passage channel.
