ABSTRACT:
A frame, more particularly for a picture, comprises profiled rails which are joined together at the corners of the frame by a corner-connector. Each corner-connector comprises two plugs arranged respectively in a cavity in each profiled rail, and each of the cavities comprises an opening extending in the longitudinal direction. The object to be achieved is a functionally reliable joint between the profiled rails which is simple to produce and can easily be released when required. To this end, each plug comprises a tongue which passes through the opening in the cavity and which engages, by means of a hook element or the like, behind a retaining element. A retaining element of this kind is arranged on at least one web of the profiled rail.
