A ring clamp capable of forming a gas-tight 360 DEG indentation in a tubing slip-joint, the structure comprises a circular cross-section which is discontinuous over a minor portion of its circumference and has a threaded bolt leg extending from a first end thereof. A tightening lug member comprised of a cylindrical tubular housing and having a planar web extending from one side thereof fits within the discontinuity in the ring, the bolt leg extending freely into the tubular housing and the other end of the ring being welded to the planar web. An inner edge of the web is arcuately formed to continue the circular arc of the ring within the discontinuity, the arcuate surface thus formed being continued by arcuately edged flared portions of the tubular housing located at the entry end of said housing where the bolt leg extends into said housing. The inner perimetric surface of the ring at said entry end lies effectively at the same point on the inner circular arc defined by the ring clamp as the innermost distal corner edge portions of the flared portions, the bolt leg being supported against outward radial movement at this locus within the tubular housing. A nut fitting on the threaded end of the bolt leg and torqued against the exit end of the housing reduces the inner circumference of the ring clamp to impress a bead in a tubing slip-joint over which the ring clamp has been fitted, the bead being formed by the pressure of the ring, the inner arcuate surfaces of the web, and the flared portions of the tubular housing, thereby to form the gas-tight joint and to secure the tubing portions together. |
