The development of a universal space frame connector is discussed in this paper. The role of the connector in facilitating the construction, assembly and member replacement or repair of space structures is described. The strength and failure behaviour of three sizes of the connector system are assessed through experimental studies. The prinipal effect of axial tension and compression and the secondary effect of bending action are investigated. Dimensions and sizes of both connectors and members are adjusted such that various modes of failure of components occur around the same level of loading. Examples of application are also briefly illustrated.
