Plug connections for electrical lines are available in the I

different versions are well known. One of the well-known testing is the SCHUKO socket outlet, which, due to its special features, has meanwhile already been prescribed for »use · the invention this socket is undoubtedly a brilliant achievement, insofar as, that it largely excludes possible sources of danger. However, the use of this socket outlet is limited because it is almost exclusively is intended for installation on the wall and is used to establish plug connections to devices and non-ceiling lights

For the purposes of the present invention, as a supplement and at the same time A safety plug-in connection was developed to complete it, mainly for lamps to be attached to the ceiling and devices. So far this has not been taken into account- ' ben that, given the current state of security conditions, none

Usable solution was found, the provable sources of danger eliminated in one fell swoop

In the present invention, which is tried and tested over the long term, is in the objective has now found this solution.

W Up until now, it was common practice for new buildings, relocations or retrofits to have bare cable ends sticking out of the ceiling at the points where, for example, lamps are to be installed, which are often not even secured by safety clips. It is not uncommon for ignorance or careless handling to lead to unwanted accidents and even injuries with fatal consequences.Only because one was not aware of the danger and the consequences and perhaps also recklessly did not remove the safety devices. Laypeople are even mostly forced to hire electricians for the simple mounting and installation of lamps · This is not only cumbersome, but also time-consuming and also associated with costs.

- All of these negative circumstances and some more on which to depend This point does not have to be discussed further, are abruptly eliminated by the present invention in its entirety. The testing of the present invention has shown the best and most positive results imaginable. .-

a) The first thing to be said is that there are already new buildings with these Elements should be equipped so that when moving into the rooms, such as the Schuko sockets, the ceiling connections for Larapen etc, are already fully installed, so that without any fuss and absolute exclusion of "any danger nioraente, with a very easy hand- · "took hold in a matter of seconds, e.g. a lamp is connected and ready for use without the fuse having to be removed. The same In the broadest sense, you can refer to all other usual electrical elements, both on ceilings and, if necessary, on walls constantly and firmly connected, will be »" ". . ■,: '■ "- ■"

b) It is just as easy when using the present invention to remove lamps, etc., for cleaning, or, for example, a T. ^ m pe to be temporarily replaced with a ceiling fan. Ea gives many more examples of this kind to be cited,
