ABSTRACT:
The expandable band is used to secure a sealing element within a generally cylindrical structure, such as a pipe or manhole, or other round hole. The expandable band includes a band body having a first band end portion and a second band end portion. The first band end portion includes a plurality of slots, and the second band end portion includes a first and second aperture. A locking member is a separate element adapted to fit within the first and second apertures and includes a first tab for extending through the first aperture and into one of the plurality of slots to lock the expandable band at the desired diameter and a second tab for engaging the second aperture. The second tab is designed not to interfere with the first band end portion while expanding the band. The locking member may also include at least one rib or protrusion.
