ABSTRACT:
A coupling or clamp for clamping a tube or a pipe. The coupling is made up of an elongated band surrounding a gasket. Two laterally spaced notches are formed in one end of the band and strikes are fixed to the other end of the band and disposed in the notches. The ends of the band on each side of the notches are bent back on themselves forming eyelets which receive a yoke. The yoke has a curved intermediate part that has a weld nut welded in it and a screw extends through the weld nut. The end of the screw engages the strike. When the screw is swung to a position generally parallel to the diameter of the tube, its end can engage the strike. Then as the screw is swung to a position tangent to the pipe, its toggle action exerts a preliminary tension on the band. Final tension is accomplished by operating the screw in a conventional manner.
