  • Tubular member coupling device
    Patent number: 6832786
    Abstract: A device for coupling tubular members including a sheet member having a first end and a second end where the first end and the second end are operatively arranged to overlap one another to form a substantially cylindrically shaped coupling, an abutment member mounted to the sheet member proximate the second end thereof, a male threaded member, a female member pivotably mounted proximate the first end of the sheet member and arranged for pivoting rotation about a pivot point, where the female member is arranged to threadably engage the threaded male member, and the male member is operatively arranged to abut the abutment member, wherein the male threaded member is operatively arranged to rotate in a first direction to abut the abutment member and expand the substantially cylindrically shaped coupling.
