ABSTRACT:
An arrangement for securing a housing cover, especially useful for securing a cover for a switch box having electrical switching devices therein includes at least one screwable element which can be threaded to the housing and which is secured undetachably on the cover by a stop on its shaft. The shaft extends through the cover, each of the screwable elements extending through a bottom of an indentation in a surface of the cover. A pre-stressed compression spring is disposed in the indentation between a shoulder of the screwable element and the base of the indentation. Each screwable element comprises a shaft nut, the shaft nut having a shaft with an indentation in its pressure-receiving face. The shaft engages with a threaded pin attached to the housing and rests against a structural part which is supported against a support attached to the housing. The screwable element is centered by a centering body positioned directly ahead of the support on the threaded pin.
