If larger opposing forces are now triggered on the cover part, © ie E.g. a picture tube on a picture frame mask, especially with Can exercise the transport of the device, simple snap devices do not offer sufficient security against undesired loosening the fasteners.

The invention is based on the object of creating a simple snap connection that. is also not released by "large forces acting from the rear, which can, however, easily be snapped into place and easily released by hand.

The invention solves this problem in that on the cover parts Resilient tabs and pockets on the parts to be covered are provided are, in which the tabs can be inserted in such a way that the tabs are bent transversely to the Sinschubrichtung during insertion and at the same time are arched in on, but are relaxed after engaging,

In particular, the invention also has the further advantage that fastening material is largely unnecessary and the passage of the belt is thereby accelerated and working time is saved when assembling the housing.

According to one embodiment of the invention, guides (in particular L-shaped guides) and in snap hooks are provided in the middle of the pockets. According to another Training dt »Invention aind the flaoh sides of the bags, in insertion funnel-shaped and sntspreehen at the end the profile of the snapper (or snap hook) to be inserted.

To ensure a tight fit even with large tolerances, According to a further embodiment of the invention, the base plate can have a recess in the area of the foot point of the snapper, which allows the sniper to deflect.

An embodiment of the invention is based on the drawing
described in more detail. Show it ί

The housing 1 of a television receiver has a base frame 2 for the picture mask frame 3, and a base frame 4 for with
Loudspeaker panel 7 provided with slots 5 and recesses 6 for the operating parts and display. On the image mask frame η 3

The pockets (FIGS. 2a, 2b) have hook - or L - shaped guides 10 for the resilient tabs 8 or snaps 11 (FIGS. 3a, 3b) at the lateral ends, and there is a snap-in hook in the middle of the pocket 12 provided. The flat sides 10 of the pocket 9 are in

Insertion direction funnel-shaped (slope 13) and correspond at the end of the profile of the snapper 11 to be inserted or the snap hook IU, so that the snap hook at the end the insertion movement behind the latching hook 12 can engage.

The deformation of the tabs or the snapper during the pushing process can be seen in more detail in Figures U and 5 *

As a result of the funnel-shaped design of the guide 10 on the one hand and the forward sliding on the incline of the insert hook 12 projecting snap hook IH on the other hand are the resilient tabs 8 or 11 bent transversely to the direction of insertion when inserted (Figure U) and at the same time arched, while at the end of the insertion movement they are relaxed and with the snap hook IU behind the locking hook 12 (FIG. 5). Even a strong pressure from the direction opposite to the insertion movement can not achieve the deformation mentioned, so that the greatest possible security against unintentional loosening of the Fascia is achieved, while this risk is achieved with a snap arrangement that only interacts with a catch or a snap-in hook would exist.

In order to have a tolerance compensation, the base plate 15 is in the area of the snapper in the illustrated embodiment elastically deformable z, B. in such a way that the base plate 15 has a recess 16 in the area of the foot point of the sniper, so that. the Schnepper can be advanced further than would be possible with a rigid arrangement.
