An installation frame for accommodating a device in a predefined installation opening is described. The installation frame has wall sections which enclose a largely cuboid cavity which is open at least on the front for accommodating the device, front edges of at least a portion of the wall sections forming flange-like outwardly projecting edge sections for resting against a front edge of the installation opening. The installation frame also has a latching arrangement which project to the outside from at least a portion of the wall sections and engage with the back of the installation opening, wherein the latching means have at least approximately arc-shaped sections which extend into the cavity and furthermore have an end section which projects to the outside through the wall sections for engaging with the installation opening in such a way that the arc-shaped sections are flattened when the device is inserted into the cavity and consequently are elongated in the direction of the back of the installation opening so that the installation opening is clamped between the front edge sections and the latching means of the installation frame. The installation frame may be easily, quickly and securely attached within the installation opening.
