ABSTRACT OF THE DISCLOSURE Extruded bars or columns of a set of structural members are each formed with a central passage and with at least one longitudinal groove having a restricted orifice. A connector member has a body portion secured in the passage of one member and two catches mounted on the body portion and projecting into the groove of another member. One catch has a leading, enlarged head portion and a reduced neck portion trailing the head portion. An operating device on the body portion includes a single, manually operable drive shaft and two motion trans- mitting eccentrics respectively connecting the shaft to the two catches for moving the catches inward and outward of the groove orifice in timed sequence so that the neck portion of the one catch together with the other catch laterally secures the catches in the orifice while the enlarged head prevents accidental withdrawal of the catches from their locking posi- tion. - 1 -
