Abstract

A fastening device for attachment of, for example, mounting rails to vertical frame profiles of a switchgear cabinet. The frame profiles have rows of evenly distributed fastening retainers. A fastening block, which has fastening retainers for connecting the mounting rail or the like, can be added to the frame profile. In order to secure fastening of the mounting rail on the vertical frame profile, which only requires a small outlay of parts, the fastening block is manufactured either as a punched and bent element from a sheet metal blank or as an extruded element. At least one hook element projects from the fastening block, which can be suspended in an associated fastening retainer of the frame profile. The fastening block has two lateral walls, which extend at right angles with respect to each other and form a common vertical inner edge facing the interior of the switchgear cabinet. The lateral walls are equipped with the fastening retainers for connecting the add-on elements.
