Claim:
A protection barrier comprising: an elongated barrier defining a chamber therein, said barrier having a base, a top surface, first and second side walls, and first and second ends, each of said first and second side walls including: a plurality of non-vertical wall segments connected end-to-end collectively defining a side wall surface; a plurality of buttresses extending vertically in spaced apart locations along said side wall surface; and a guide channel being inwardly curved in said side wall surface of said first and second side walls, said guide channel being horizontally disposed to extend between each one of said plurality of buttresses, said guide channel positioned in horizontal alignment with a similar sized guide channel on like-configured barriers; a coupling disposed on each opposed end of said barrier, each coupling being like-configured for each opposed end thereby said coupling is releasably connectable in juxtaposed end-to-end arrangement to either opposed end of like-configured barriers; said coupling including a tongue extended from each opposed end of said barrier, said tongue extending vertically between said base and said top surface of said barrier, said tongue extended from an off-center portion of each end; a groove indentation in each opposed end, said groove extending vertically between said base and said top surface of said barrier, said groove and said tongue having one contiguous surface; and each opposed end of said barrier having beveled corners providing for pivotable movement of said tongue of a first barrier end relative to a second groove of a like-configured second barrier end when said tongue of either end of said first barrier is removably inserted into said second groove of either end of the like-configured second barrier thereby forming an end-to-end aligned and nesting relationship of a plurality of like-configured barriers.
