ABSTRACT:
The present invention relates to water-pump pliers having two plier handles which cross each other and are connected to each other by a pivot pin 7 whereby the handles form plier jaws above the region of crossing of the handles and grip sections below the region of crossing of the handles, and in which the first plier handle is adjustable in steps relative to the second plier handle to change the size of the plier jaws. The pivot pin is fitted and guided in a bore defined in the first plier handle and enters into form-locked engagement with the profiled flanks of a slot in the second plier handle, where the slot lies in the crossing region of the handles, and, in order to obtain a structural form which is simple to manufacture, favorable in operation and stable in use, the pivot pin is rendered incapable of turning with respect to the second plier handle.
