ABSTRACT:
A hand operable tool designed for use in connecting tube ends to couplers and like elements commonly used in lawn irrigation equipment. The tool comprises a head portion disposable between an open and closed position by the manipulation of handles wherein the distal ends of two arms of the head portion are bifurcated so as to effectively surround and retain ends of tubes so as to force, through clamping such tubes into attachment with an interconnecting coupling member, tee member, etc. The second gripping portion on the gripping head is designed to clamp between the arm the coupler, tee member, etc., to cause removal thereof from one or both of the tube ends wherein use of the tool greatly facilitates the reduction of effort and time in the assembly or disassembly of tubes and tube fittings in lawn irrigation equipment.
