ABSTRACT:
A framework comprises bars coupled together by a coupling carried by some of the bars (carrier bars). The other bars have undercut longitudinal slots which receive coupling ends of the coupling. The coupling includes a bearing member on which is mounted an eccentric member which is rotatably accessible from one face of the bar, and a holding member which can be displaced longitudinally and laterally in response to rotation of the eccentric member. The holding member has a hook-shaped coupling end which, in the coupled position, engages in the undercut longitudinal slot in the other bar. The holding member comprises a tongs-shaped leaf-spring comprising a pair of arms joined at one end by a web. The leaf-spring surrounds the bearing member. The holding member includes a recess for housing the eccentric member. The outer end of the bearing member has a wedge portion which extends as far as the longitudinal slot in the other bar when the bars are connected. An inside surface of the leaf-spring is engaged by the eccentric member whereby the arms of the leaf-spring can be forced against the wedge to spread the arms apart and into locking engagement with the slot of the other bar.
