A pipe section in a pipe is quickly sealed with a hardenable, partially hardened, flat insert mat or prepreg. Adhesive is applied at least to the outer surface of the insert, adhesive is introduced between two superposed end regions of the insert, and to insert is given the form of a cylinder jacket. The insert is placed on an elongated balloon, a part of the insert is placed against the balloon and its jacket continuously covered at least in a partial area, and the remaining region of the insert which does not adjoin the balloon is turned into a loop and pressed against the outer surface of the insert. The balloon with the insert is inserted into the pipe and positioned at the leak or weak location. Then the balloon is inflated, such that the insert is pressed against the inside wall of the pipe and the adhesive is hardened.
