The mounting frame arrangement is assembled from profile frame sections and connectors and is used for control panel assemblies, for component racks and holders, in household wiring, for equipment cabinets, and the like. On the four-sided (preferably square) hollow profile, one side has a longitudinal slit and at least the two adjoining sides each have openings opposite one another and distributed at regular intervals. The disconnectable connectors have two pairs of legs opposite one another and spaced apart by an adjustable distance, which are insertable in a form-locking manner into the interior of the profile. By being spread apart by spreader devices, the legs are made to contact opposed inside walls of the profile. At the same time, as locking means for preventing longitudinal displacement, detent protrusions come to engage the openings. A transverse groove for the same purpose is also possible on the outsides of the legs and on the inside of the profile. Several variant profiles and connectors as well as specific embodiments of the spreader devices are described.

An adjustable mounting frame arrangement comprising: four-sided hollow profile sections having at least one longitudinal slit on one side of the sections, and locking means at least on the sides adjoining the side having the longitudinal slit, preventing longitudinal displacement; disconnectable connectors for connecting two such profile sections together, wherein the connection is affectable by spreading action at the connectors; said connectors having two pairs of legs provided with at least one spreading device, the width of the legs transverse to the spreading direction being adapted to the inside width of the profile; detent devices located on the outside of the legs which come into engagement with said locking means upon spreading and substantially at the same time to effect form locking with the four inside walls of the hollow profile, wherein the height of the legs, including the detent devices, is less than the width of the at least one longitudinal slit, the legs each being individually insertable into the interior of one hollow profile section through the longitudinal slit.
