The illustrated in the figures, here preferably as a wall-hung and thus accessible from below heater, especially as a boiler, trained device consists of a housing 1 for a protected from external access device, such as combustion chamber, burner or automatic burner inside the housing 1. In this case, the housing 1 has a access to the interior of the housing 1 in the open position releasing and in the closed position preventing, preferably formed from sheet metal housing part 1.1. In addition, the housing 1 is provided with a closure element 2 which can be brought into the closure position without tools, ie. H. It is readily possible to close the housing 1 without any tools.

Furthermore, it is provided that the closure element 2 is formed in the closed position of the housing part 1.1 from outside the housing 1 without tools inaccessible.

Essential for the inventive solution is now that on the housing 1, an optionally thin and / or longer than an average human finger trained channel 3 is arranged to receive a rod-shaped tool, d. H. the opening of the housing 1 with his bare hands is reliably prevented by the proviso of the invention. The channel 3 is preferably formed vertically extending and open at the bottom opening out.

It is furthermore particularly preferred, as is known from the FIGS. 2 and 3 it can be seen that the housing part 1.1 has a thin-walled wall area 1.1.1 cooperating with the closure element 2.

Furthermore, it is preferably provided that the closure element 2 has an insertion region 2.1 for the wall region 1.1.1.

In this insertion region 2.1 is preferably a cooperating with an opening 1.1.2 on the wall portion 1.1.1 locking element 2.2 is arranged. How out FIG. 3 can be seen, the locking element 2.2, the opening 1.1.2 on the wall portion 1.1.1 formed in the closed position by cross.

Furthermore, it is particularly preferably provided that the channel 3 is designed to open in the closed position in the region of the opening 1.1.2 of the wall region 1.1.1.

With regard to the latching element 2.2, it is furthermore preferably provided that, in a first position, it passes through the opening 1.1.2 on the wall area 1.1.1 (see FIG. 3 ) and in a second position removing the wall portion 1.1.1 is made possible from the insertion 2.1 permitting (see FIG. 2 ).

As is clear from the FIGS. 2 and 3 results, it is further preferably provided that a direction of movement of the locking element 2.2 between the first and the second position is parallel to the main longitudinal axis of the channel 3 extending.

• Ausgangspunkt der Beschreibung sind Figuren 1 und 3, also das geschlossene Gerät, das geöffnet werden soll, was aber erfindungsgemäß ohne Werkzeug nicht möglich ist. Vielmehr ist ein langes, dünnes Werkzeug erforderlich, dass von unten in den Kanal 3 eingeführt wird, und zwar so tief, bis es die Vertiefung 2.2.1 am Rastelement 2.2 erreicht.

The device according to the invention works as follows:

• Starting point of the description are FIGS. 1 and 3 So the closed device that is to be opened, but according to the invention without tools is not possible. Rather, a long, thin tool is required that is introduced from below into the channel 3, and indeed so deep until it reaches the recess 2.2.1 on the locking element 2.2.

This touch feels the installer (or the like). Knowing the operation of the solution according to the invention, he knows that he now has to press up against the tool in order to move the locking element 2.2 against the force of the spring element 2.3 upwards. At the same time a built in the housing part 1.1, acting on pressure against the device 1 generates Sealing element 1.2 in the direction of unlocking (away from the device 1) acting force that moves the housing part 1.1 so far that the housing wall 1.1.1 automatically moves under the locking element 2.2, so that a return movement of the locking element 2.2 in this position more is possible because it rests above the housing wall 1.1.1. The tool can thus be removed after a single defined operation, without the housing part 1.1 falling back into a locked state. It remains in an unlocked state and can be easily removed. FIG. 2 shows this state, but here is the housing part 1.1 already pulled out a little further from the insertion 2.1.

To close the device you push the wall area 1.1.1 easy in the insertion 2.1. This leads first to a lifting and then to a latching of the locking element 2.2 in the opening 1.1.2.
