Abstract: An adjustable width split sleeve adapted to be securely wrapped around an elongate member. The sleeve includes a pliable laminated sheet having a first end and a second end. Each end of the sheet is wrapped around a respective first rod. Each first rod is rotated about a second rod which is parallel and adjacent to the first rod but which is separated from the first rod by the sheet. The first and second rods may be positioned various distances from the edges of the sheet as desired to provide a desired width of the sleeve and to provide a tongue to seal the gap between the sheet ends. By positioning the rods in this manner, the rods on each end of the sheet, which are floating and not restrained nor clamped, will lock together from the tension applied to the sheet when the sleeve is secured around the elongate member. Each end of the sheet is securely gripped between the respective first and second rods.
