Abstract
A method for holding together the opposing ends of a flat sheet wrapped around an elongate substrate employs one or more closure devices, each closure device comprising a pair of frictional elements and a means for interengaging same. The frictional elements each have a channel member having a slit and a rod member positionable within said channel member, which when so positioned cooperates therewith to provide a conduit thereinbetween and to apply frictional forces to one end of the flat sheet when the end has been inserted through the slit and is in position between the rod member and the channel member. The closure is especially suited for joining elastomeric flat sheet, the sheet and closure device or devices collectively providing a protective closure.
