Abstract
Herein presented is a device for shutting off the flow through a pipe. The device is basically a pincers tool with two jaws and two handles. It, however, has special and unique features that make it rugged, reliable, efficient and easy to use. It has compound leveraging. It has pivotal features that allow the inner surfaces of its jaws to remain parallel to one another as the jaws are opened and closed. A latching and releasing mechanism permits the locking of the handles once the jaws have reached a desired closed position.
