Abstract
Disclosed is a line clamping device which may be remotely and repeatedly operated to clamp line passing through the device. Increasing pressure acting on a piston in the clamp housing moves slips to a position clamping the line while compressing a spring. When pressure on the piston is reduced, the spring moves the slips and piston to back to a position not clamping line.
