<p>A corner connecting arrangement for lengths of profile (1) or similar elements which are provided with cavities and can be connected at an angle to each other, and which can be releasably connected by means of connecting devices. The invention makes it possible to connect together lengths of profile (1), etc. which have a cavity, at an angle to each other irrespective of the cross-section shaping of the said cavity. A connecting piece (4) which has at least two projections (9) disposed at an angle to each other extending out from a common intermediate part and provided with a sloping connecting surface (21), is provided with an abutment surface (12) appertaining to each of the projections which is designed to co-act with a corresponding screw device (6) which can co-act with a wedging element (5) which can be displaced over the connecting surface of the said connecting piece and which is designed to move over the said connecting surface (21) when the associated screw device is screwed in or out, thereby increasing the effective width of the projections in one screwing direction in order to achieve clamping co-action with the length of profile (1), and reducing the said width in the opposite screwing direction in order to effect disengagement.</p> |
