A frame for front insertion of pictures and the like has a plurality of elongated frame elements which have inclined edges and are movable relative to one another between a proximal position and a distal position, and a plurality of connecting elements each connecting a pair of the frame elements in their corner region and including an angled member insertable into each pair of the neighboring frame element so that the latter can move over the angled member between these positions, a supporting member connected to the angled member and extending inside the frame so as to support pictures and the like, and two arresting members arranged to engage with and arrest the frame elements in each of these positions.
