 the pipe wall is curved and the bracket ends are beveled, for the purpose of achieving a tight fit of the bracket with the least possible change in the shape and size of the free pipe cross-section without the formation of a special stop surface in the pipe wall.



   The drawing shows a cover closure designed in accordance with this innovation, namely FIG. 1 shows the cross section through the tube with the cover inserted, while FIG. 2 shows a plan view.



   The cover to be pressed into the sleeve e with the interposition of a seal c is equipped with the locking bracket f shaped according to the invention, which is rotatably guided in the cover by the handle 9 designed as a screw spindle and screwed on and off by means of the handle provided with nut li can. The cover is inserted with the bracket in position f1 (Fig. 2) and after turning the bracket into the position / by screwing up the latter, it is tightly pressed in.



   In order to prevent the thread 9 from rusting in as far as possible, it is expediently designed as a so-called Schndrig thread with a shallow thread depth and a significant thread pitch.
