    • The novel method is used to renovate or close connections in a pipeline (12), in particular in drains, especially after the main and/or connecting pipe (16) has been relined. The method comprises the following steps: introducing and positioning a shuttering sleeve (22) with a recess and bores (28) corresponding to the connection aperture for pressing in a hardenable, and possibly resilient, mortar, preferably epoxy mortar, in the main pipe; introducing the expandable rubber balloon (34) so that its outer part lies in the still-intact part of the connection pipe (16), its central part lies between the connection pipe and the recess in the shuttering sleeve, and its part containing the fluid delivery point lies in said recess and in the main pipe; expanding and positioning said expandable rubber balloon so that it delimits a space either between the bored-out end of the connection pipe, the recess in the shuttering sleeve and the surrounding soil, or simply between the bored-out end of the connection pipe and said recess if the previously projecting connections have been milled off, said space then being filled with a hardenable, and possibly resilient, mortar, preferably epoxy mortar; and, when the mortar has set, optionally removing and extending both the shuttering sleeve and the expandable rubber balloon which has been rendered pressure-free.
