The invention relates to a device (1) in connection with connecting parts (2) for releasable connection of adjoining end portions (3, 4) of furniture ends (5, 6), scaffolds or other connectable parts, and for supporting objects (7), and which is formed by an end coupling part (8) provided with opposite receiving apertures (9, 10), which are angled (X) in relation to one another.
Thereby, a vertically (11) extending fastening part (12), which has receiving accommodation (13) with laterally (14) extending, slot-shaped aperture (15), is integrated with said connecting part (2). A supporting part (17) exhibiting a thickened dolly part (16) can be displaceably received in said receiving accommodation (13), and can with intermediate connecting web (18) be received in said slot-shaped aperture (15). Thereby, the fastening part (12) is arranged to be kept on a desired set level (19).
