The invention contemplates support structure for a conduit or the like wherein one of two cylindrically arcuate metal band parts incorporates mounting-bracket or foot structure and the other such part has articulated connection to one, and releasably tensed connection to the other, of the ends of the bracket-carrying cylindrically arcuate part. A liner of flexible resilient material extends circumferentially continuously within the metal-band parts between the releasably connected ends thereof. The releasably tensed connection includes an over-center latch and a redundant safety latch, and in each of the disclosed embodiments mounting-foot structure is integrally formed with one of the metal-band parts.

1. A draw-band line support comprising two cylindrically arcuate metal bands having articulated connection at one end of their adjacent ends and coacting tension-clamp connecting means releasably interconnecting their other adjacent ends, radially outward mounting-bracket structure on one of said bands, and a single continuous liner of flexible resilient material of generally C-shaped section with retaining flanges retained to both bands, said liner extending circumferentially continuously within said bands from and between said other ends thereof, said liner continuously spanning the region of articulated connection, there being a short discontinuity of said flanges at the region of band articulation, and being adapted to accommodate an articulated opening of said bands to at least the extent of the diametral span of the bands when said other ends are releasably clamped. 2. A draw-band line support comprising two cylindrically arcuate metal bands having articulated connection at one of their adjacent ends and coacting tension-clamp connecting means releasably interconnecting their other adjacent ends, radially outward mounting-bracket structure on one of said bands, and a continuous liner of flexible resilient material extending circumferentially continuously within said bands from and between said other ends thereof, said liner being of generally C-shaped section with retaining flanges circumferentially lapping the outer surfaces of said bands, there being a short discontinuity of said flanges at the region of band articulation. 3. The support of claim 2, in which said one band comprises two cylindrically arcuate portions each with an integrally formed radially outward arm portion, said arm portions being secured in mutual abutment to define said mounting bracket structure. 4. The support of claim 3, in which said cylindrically arcuate portions are of substantially equal extent and said arms include an angularly bent outer mounting portion at radial offset from said arcuate portions. 5. The support of claim 4, in which said angular bend is at substantially 45° to said radial arm portions. 6. The support of claim 3, in which said liner has a second short discontinuity of said flanges at the region of said arm portions. 7. The support of claim 2, in which said articulated connection comprises a hook formation on one of said bands and a slot formation on the other band. 8. The support of claim 2, in which said releasable connecting means comprises a hook formation on one of said bands, a loop formation on the other band, and hasp structure comprising a lever pivoted to said loop formation, said lever carrying a bail at radial offset from the lever-pivot axis, said bail being engageable with said hook formation, and said lever being formed to seat against the exterior of said other band and, when in approach to seated relation, to carry the point of bail-lever connection past the dead-center alignment of said lever-pivot axis and of bail-hook engagement. 9. The support of claim 8, in which said lever and said other band have releasable snap-lock formations engageable to releasably retain the seated position of said lever. 10. A draw-band line support comprising two cylindrically arcuate metal bands having articulated connection at one of their adjacent ends and coacting tension-clamp connecting means releasably interconnecting their other adjacent ends, mounting bracket structure including a generally radially outward integral arm formation on one of said bands, and a continuous liner of flexible resilient material extending circumferentially continuously within said bands from and between said other ends, said liner being of generally C-shaped section with retaining flanges circumferentially lapping the outer surfaces of said bands, there being a short discontinuity of said flanges at the region of band articulation. 11. The support of claim 10, in which said arm formation includes an angularly bent outer mounting-foot formation. 12. The support of claim 11, in which said foot formation is locally flat in a mounting region thereof for mounting abutment to a flat mount surface, the geometrical plane of said locally flat region being substantially tangent to the outer circumference of said support within the arcuate span of said one band. 13. The support of claim 10, in which said integral arm formation is at the releasably clamped end of said one band. 14. The support of claim 10, in which said releasable connecting means comprises a hook formation one one of said bands, a loop formation on the other band, and hasp structure comprising a lever pivoted to said loop formation, said lever carrying a bail at radial offset from the lever-pivot axis, said bail being engageable with said hook formation, and said lever being formed to have a seated position in approach to the exterior of said other band and, when actuated in the direction of said approach, to carry the point of bail-lever connection past the dead-center alignment of said lever-pivot axis and of bail-hook engagement. 15. A draw-band line support comprising two cylindrically arcuate metal bands having articulated connection at one of their adjacent ends and generally radially outward angularly spaced confronting integral arm formations at their other adjacent ends, coacting tension-clamp connecting means for releasably interconnecting said arm formations at radial offset from the geometrical cylinder of said metal bands, and a continuous liner of flexible resilient material extending circumferentially continuously within said bands and between said other ends thereof, said liner being of generally C-shaped section with retaining flanges circumferentially lapping the outer surfaces of said bands, there being a short discontinuity of said flanges at the region of band articulation. 16. The support of claim 15, in which one of said arm formations includes a flat mounting foot region within said radial offset.
