ABSTRACT OBJECT To provide a tube for covering a connection of electric wires, which can be quickly fitted to the connection without using any heat source and can provide reliable moisture resistant, electrically insulating, and mechanically protecting properties. STRUCTURE A covering tube 10 has a tubular sleeve section 12 made of a flexible electro-insulating material, and electro-insulating tubular sealing sections 14 provided at the ends of the sleeve section 12. The sealing sections 14 include elastically shrinkable elements 16 formed integrally with the sleeve section 12, and core elements 18 arranged within the shrinkable elements 16 so as to hold the shrinkable elements 16 in an expanded state with a predetermined diameter. The elastically shrinkable elements 16 are made of rubber materials having electro-insulation, high elastic recovery, and excellent elongation set properties. When the core elements 18 are removed upon being fitted to the connection, the elastically shrinkable elements 16 are brought into close contact with the outer surface of the cable sheaths due to an elastic recovery force of the shrinkable elements.
