ABSTRACT:
A protective plastic sleeve device is provided to be wrapped around, and hence to seal, the juncture along a joined series of elongated pipes, cables, conduits or similar members. The sleeve device includes a plastic sheet whose end portions are folded back and attached, to form a pair of passageways. Rods extend through each of the passageways. Apertures are provided along the end portions to communicate with the passageways. Engagement means, advantageously in the form of alternative male and female members, project from the rods through the apertures to interlock the rods together and hence retain the end portions of the sheet in juxtaposed confronting relationship.
