Abstract: Increased resistance to displacement of a barrier or barrier sections thereof in response to a lateral force without anchoring or bolting barrier sections together is achieved by providing an attachment arrangement near the top of an end of barrier sections which is capable of carrying a tensile force and developing that tensile force using a tightening bolt/nut arrangement located at deflection stops at lower corners of the barrier sections to develop a compressive force.

The tightening bolt/nut arrangements are retained by and are captive to the respective barrier sections when barrier sections are disassembled from each other.
