Abstract: A vertical pipe holding tool comprising a flat base member and a forked member. The base is slotted such that it can be fit around a vertically disposed length of pipe, and includes projecting members having a vertical side adjacent the slot. Two of the projecting members are relatively disposed at a predetermined angle. The forked member includes arms having vertical exterior sides relatively disposed at the predetermined angle, and adjacent interior sides forming a predetermined angle, preferably 55.degree.. The exterior surface of the forked member arms engage the interior surface of the base projection members to form a generally triangular aperture of such dimensions as to permit passage of pipe but restricting passage of pipe couplings. The apex of the triangle provides for passage of electrical cables fixed to the pipe exterior. The engagement between the projecting members and forked arms prevents accidental disengagement due to jostling.
