Abstract
Abstract A longitudinally divided cable sleeve characterized by a strip-like sleeve member which is composed of a heat-shrinkable material and has two longitudinal edges with reinforcing inserts to form first and second edges with reinforced portions, and coacting closure elements for joining the edges together with the elements on the first edge being bent from strips of material and having a head portion that is received in a slot or opening in the second edge. Preferably, each of the elements bent from a strip of material has a link portion, which is received in a slot of the first edge up to an abutment surface and a projecting closure part which is inserted through the opening of the second edge is provided with a latch element to prevent accidental and unintentional disassembly of the closure elements after the projecting closure part is inserted through the opening of the second edge.
