[ What is claimed is:] [1.] An attachment system for attaching first and second boom members of a split-boom power tool, the attachment system comprising:a coupling attachable to the first boom member and comprising a substantially cylindrical single-piece joint having first and second ends, said joint having a cylindrical diameter and being compressible for reducing the cylindrical diameter, said coupling further comprising first and second flanges extending from the joint, and a first tightening member engaged with said first and second flanges for selectively decreasing the cylindrical diameter of said joint at said first end of said joint, said cylindrical joint further comprising a radial aperture formed through a cylindrical wall of said cylindrical joint;a resiliently biased locating pin connectable to the second boom member for engagement with said radial aperture to secure the second boom member to said coupling; andwherein said first tightening member is configured to squeeze said first and second flanges together to decrease said cylindrical diameter to rigidly secure the second boom member within said joint.
