Abstract
Abstract A connector (10) interposed in a support element (L) by attachment to first and second displaced ends (L 1 , L 2 ) thereof to selectively permit an object to pass transversely through the longitudinal axis of the support element while employed to brace a structure including a first linkage (12, 113) connected to the first end (L 1 ) of the support element, a second linkage (11, 114) connected to the second end (L 2 ) of the support element, and means for coupling the first and second linkages (14; 111, 112) being attached to said first linkage and the second linkage and having a receiver (16; 111, 112) selectively opening to either side of the support element to permit an object to pass transversely through the longitudinal axis of the support element.
