Abstract
A wrap-around closure assembly for elongate objects such as pipelines including a length of heat recoverable material as the closure member and a fastening device extending lengthwise along the elongate object for holding the edges of the material in a nearly abutting relationship. The fastening device has channels which receive the edges of the heat recoverable material such that the retaining forces of the fastening device are in line with the tensile forces of the recovered closure member. Retaining means within the channels prevent the withdrawal of the edges during assembly and after heat recovery of the closure member. The legs of the channels are also forced against the interposed closure member to prevent extraction thereof.
