  • one end of the band is folded about the seal, the band is wrapped around an item and the free end of the band is placed through the opening in the seal, thereby interconnecting both ends of the band to the seal.
  • the excess portion of the free end of the band is then cut and a portion of the free end is bent about the seal to secure the band to the seal, which maintains a predetermined band tension about the secured object(s).
  • Some seals of the prior art include a selectively positionable protrusion, i.e., a
  • wing that is used to secure the free portion of the band to the seal.
  • the wings are selectively bendable and secure the free end of the band adjacent to an exterior surface of the seal. Seals of this type are commonly used for low tension, light duty applications, for example, to interconnect insulation around a pipe. After a predetermined tension is applied to the band, the free end is folded over a top portion of the seal, the wings are folded over the folded portion of the band, and the excess portion of the free end extending beyond the wings is cut from the band. Any portion of the free end that extends past the folded wings may be curled back over the wings to enhance the engagement of the band to the seal.

  • the wings of some embodiments of the present invention are over 40% easier to deform than those of the prior art seals.
  • the wings of some embodiments of the present invention have a rounded shape having smooth corners as opposed to sharp corners that help prevent user discomfort, pain or injury.
