Disclosed is a clip for spacing concentric ducts or tubes one from the other. The clip includes an elongated strip of sheet metal bent medially of its length to define a first apex and a pair of segments symmetrical on opposite sides of a plane. Each segment includes a first segment portion extending away from the apex and plane, a second segment portion extending toward the plane and defining with the first segment portion a second apex, and a semicircular flange at its end. The clip is disposed between the concentric inner and outer tubes forming the duct assembly at spaced axial positions therealong. The apices and flanges engage the outer tube and the segment portions engage the inner tube. The clip serves to minimize heat transfer between the tubes, and accommodate thermal expansion and contraction of one tube relative to the other while maintaining concentricity and providing substantially unimpeded flow through the annular space between the tubes.

A clip for spacing inner and outer tubes substantially concentrically one relative to the other, comprising: an elongated strip of resilient material formed substantially medially of its length to define a first apex and a pair of angularly related segments substantially symmetrical one to the other

A clip for spacing inner and outer tubes substantially concentrically one relative to the other, comprising: an elongated strip of resilient material formed substantially medially of its length to define a first apex and a pair of angularly related segments substantially symmetrical one to the other on opposite sides of a plane bisecting the angle formed between said segments, each of said segments including a first segment portion extending from said first apex in a direction away from said plane of symmetry and at an acute angle relative thereto, a second segment portion extending from the end of said first segment portion remote from said apex and in a direction toward said plane of symmetry to define with said first segment portion a second apex, and a third segment portion reversely formed adjacent the end of the second segment portion remote from said second apex to end in a direction away from said plane of symmetry to define a bearing surface, said third segment portions being spaced one from the other on opposite sides of said plane of symmetry, whereby, upon resilient movement of said first, second, and third segment portions on respective opposite sides of said plane of symmetry toward the plane of symmetry and disposition of said clip in the annular space between said inner and outer tubes, said first and second apices and said bearing surfaces are adapted to resiliently bear against the outer tube and the first and second segment portions of each segment are adapted to resiliently bear against the inner tube.
