Socket formwork for the production of push-in sockets on pipes, the push-in socket consisting of a flexible sealing ring (1) which is fitted in the wall of the socket (4) of the finished pipe and can be attached, as desired, at different axial positions and/or with different axial dimensions to the same undersocket (9) before production of the pipes. (Fig. 1 and Fig. 2) In this way, necessary changes in the axial position of the sealing ring (1) in the socket (4) and/or in its axial dimension can be made, in accordance with the function, e.g. for reasons of flexibility or sealing reliability, without the need to purchase new sets of slightly differently shaped undersockets (9) in each case. <IMAGE>
