    • A heat shrinkable covering in the form of a sheet which is heat shrinkable in a longitudinal direction, and a stiffening member connected at each of two longitudinally spaced transversely extending superimposable zones of the sheet. One stiffening member has holes and the other studs in the form of arm portions which are insertable through the holes to secure the stiffening members together. The arm portions can be flattened down onto the outside of the covering to retain the stiffening members together while reducing risk of the studs interfering with items such as cables adjacent the covered article. Preferably the studs have a resiliently compressible head portion which snap fits into holes formed through the sheet adjacent the holes in the stiffening member to facilitate locating the overlapped zones of the sheet relative to one another. In use, the sheet is wrapped around an article, the stiffening members are engaged together, and the sheet is then heat shrunk. The stiffening members support the juxtaposed edges of the sheet at points intermediate the coupling points, thus resisting the tendency for the edges of the sheet to separate as a result of the hoop stresses generated in the sheet on shrinking.
    • 一种以纵向热收缩的片材形式的热收缩覆盖物,以及连接在片材的两个纵向间隔的横向重叠区域中的每一个上的加强件。 一个加强构件具有孔,并且另一个螺柱形式为臂部分,其可以通过孔插入以将加强构件固定在一起。 臂部分可以被平坦化到覆盖物的外部,以将加强构件保持在一起,同时降低螺栓干扰诸如邻近被覆盖物品的电缆的物品的风险。 优选地,螺柱具有可弹性压缩的头部,其卡扣配合到通过邻近加强构件中的孔的片材形成的孔中,以便于将片材的重叠区域相对于彼此定位。 在使用中,片材被卷绕在物品上,加强件接合在一起,然后片材热收缩。 加强构件在联接点之间的点处支撑片材的并置边缘,从而抵抗由于在收缩时在片材中产生的环向应力而使片材的边缘分离的倾向。
