Abstract
A tube bender comprising a mandrel, a forming member connected to the mandrel for coaction with the mandrel to effectuate at least 180 degree bending of a tube wherein the forming member has at least two bending positions defined thereon, a handle pivotally connected to the forming member, a release member movable relative to the handle wherein the release member is associated with the handle, and engagement means for securing the release member in a locked position relative to the forming member when the handle is selectively moved to any of one the at least two bending positions thereby preventing relative movement between the handle and the forming member. The release member enables an operator to move the release member to an unlocked position to permit such operator to move the handle relative to the forming member between the at least two bending positions.
