  • Automotive hose clamp removal tool
    Patent number: 6634258
    Abstract: A manual trigger actuated automotive hose clamp release mechanism includes a flexible cable in a flexible tube. The cable and tube are attached respectively to opposed jaws designed to engage the end tabs of an automotive hose clamp and effect release of the hose clamp in response to movement of the cable relative to the tube. Mechanical advantage is gained by use of the manual trigger mechanism connected to the tube and cable in a manner enabling movement of the telescoping cable relative to the tube through which the cable extends thereby effecting movement of the jaws to release a hose clamp.
