In a device for releasably connecting the girders of framework structures, claws (3) are mounted at the free end of each girder, the claws engaging in recesses (9) of joint plates (4, 5) connectible by means of a screw (6). The joint plates (4, 5) are formed as circular discs one of which has a central through opening for a screw and another of which has a central threaded bore for the screw (6), the discs having the recesses (9) in their faces directed towards one another, concentric with the central opening or bore. The claws (3) of the girder are formed by projections in the form of circular sectors having a claw (3) at each side, curved to correspond to the configuration of the grooves, the claws being insertable between the joint plates, (4, 5), and being engageable in the recesses (9) of the plates. <IMAGE>
