Tool for applying clips

A closure tool for closing heavy-duty clips as used for example in the building trade and in agriculture has a body, a pair of handles mounted on the body on pivots and a pair of anvils movable relative to each other from a spaced position to closure position in response to relative movement of the handles and the body. A moving member is engaged by the handles and is movable therewith, and one of the anvils is connected to and movable with the moving member. The handles may have spigots engaged in a slot in a cylindrical moving member in a barrel part of the body, or each handle may have a quadrant shaped first gear engaging a rack second gear moving member slidably mounted in the body.
