A power tool coupling system for coupling two boom members (14,16) of a split-boom power tool (10). The coupling system includes a first section (44) and a second section (46). The first section is adapted to be fixedly attached to an end of a first one of the boom members. The first section includes an aperture (60) for receiving a locating member (38) on a second one of the boom members. The second section is movably connected to the first section. The second section is adapted to depress the locating member, while the locating member is located in the aperture of the first section, when the second section is moved from a first to a second position.
