FIELD: electricity.
SUBSTANCE: present invention relates to a flat corner or retractable device, meant for fitting between bases, at least two sections of a wiring duct, forming an angle between them in one plane of the bearing surface. The device has area (100) for joining the bottoms of the bases, which has central part (110) and at least one lateral part (120), joined to the central part through at least, one flexible joint (123), so as to retain mobility relative the central part. The central part has apparatus (114, 115) for fastening to the bearing surface, and the above mentioned area is made such that, the said lateral part retains mobility relative the central part after fastening it to the bearing surface, and also has provision for pressing against the edge of one of the above mentioned bases.
EFFECT: more accurate location of the central part and lateral part relative the bases, which makes installation easier.
