Kit for reconstructing a pipe connection, ▪ comprising a pipe socket referred to as the reconstruction socket which is provided for insertion into a damaged connection opening of a pipe, ▪ a sealing plate for placing against the inside of the wall of the pipe, which sealing plate has two layers, of which a first layer is formed as a sealing layer facing the wall and made of a first material, and a second supporting layer facing away from the wall consisting of a second material which is harder compared to the sealing layer, and where the sealing plate is designed to fold like a hinge around a bending line in such a way that, in its first folded state, it is of a smaller size which allows it to pass through the reconstruction socket, and in its second unfolded state, it is of a larger size such that it extends beyond the reconstruction socket in a radial direction around the entire circumference, ▪ a tensioning element which adjoins the supporting layer of the sealing plate and extends out of the interior of the pipe outwards through the reconstruction socket ▪ a supporting yoke which, with a crossbar, spans the reconstruction socket and has two legs which extend to the pipe on the outside of the reconstruction socket, where the tensioning element is mounted on and transmits its force to the supporting yoke in such a way that it transmits its tensile force to the supporting yoke thereby pressing the sealing plate against the inside of the pipe wall, ▪ an outer collar which surrounds the reconstruction socket which, firstly, lies close against the pipe and secondly against the reconstruction socket and which has a filler opening accessible from the outside, ▪ and a liquid sealing agent which can be poured through the filler opening into a sealing gap which extends in the area of the damaged connection opening between the pipe and the reconstruction socket and between the outer collar and the outside of the pipe. ▪ comprising a pipe socket referred to as the reconstruction socket which is provided for insertion into a damaged connection opening of a pipe, ▪ a sealing plate for placing against the inside of the wall of the pipe, which sealing plate has two layers, of which a first layer is formed as a sealing layer facing the wall and made of a first material, and a second supporting layer facing away from the wall consisting of a second material which is harder compared to the sealing layer, and where the sealing plate is designed to fold like a hinge around a bending line in such a way that, in its first folded state, it is of a smaller size which allows it to pass through the reconstruction socket, and in its second unfolded state, it is of a larger size such that it extends beyond the reconstruction socket in a radial direction around the entire circumference, ▪ a tensioning element which adjoins the supporting layer of the sealing plate and extends out of the interior of the pipe outwards through the reconstruction socket ▪ a supporting yoke which, with a crossbar, spans the reconstruction socket and has two legs which extend to the pipe on the outside of the reconstruction socket, where the tensioning element is mounted on and transmits its force to the supporting yoke in such a way that it transmits its tensile force to the supporting yoke thereby pressing the sealing plate against the inside of the pipe wall, ▪ an outer collar which surrounds the reconstruction socket which, firstly, lies close against the pipe and secondly against the reconstruction socket and which has a filler opening accessible from the outside, ▪ and a liquid sealing agent which can be poured through the filler opening into a sealing gap which extends in the area of the damaged connection opening between the pipe and the reconstruction socket and between the outer collar and the outside of the pipe.
