Abstract: The invention relates to a mounting system for fitting fixing elements on a wall. The aim of the invention is to allow easy mounting of fixing elements, in a cost-effective manner and with simple means, especially in rooms provided with tiles or similar wall coverings. For that purpose, the inventive mounting system comprises a base body constituting a fixing element and having at least one filling opening for introducing a bonding and fixing agent between the wall and the fixing element. The base body also has openings for penetration and distribution of the bonding and fixing agent. The base body and/or its back side oriented towards the wall are designed so as to be fluid- and gas permeable.

Abstract: This invention relates to a piping connector, which is used, in particular, for the provisional closing off of water connections in buildings under construction. To make possible a specified flushing of the pipes closed with the sealing plugs, the piping connector exhibits a housing which can be connected to a piping connection point, with a screw-on connector on one end so that it can be screwed to the piping connection point in question, and a water shut-off mechanism on the opposite end, which is protected by means of a screw-on cover.
