Abstract
The present invention relates to a one-piece tubular clamping assembly formed from a plastic type material and comprising a first clamping arm engageable with a flange positioned on a second clamping arm to create a unique lever and fulcrum structure capable of securing one or more concentric tubular members in place or blocking a flow path through a tubular member. The present invention further comprises a novel locking mechanism for preventing accidental disengagement of the clamping assembly.
