PROBLEM TO BE SOLVED: To provide a cable connecting member for use in cold climates, which can apply a common rubber insulating tube to several types of cables having different outside diameters and achieve excellent insulating performance without deteriorating a mechanical strength even in cold climates having low environmental temperatures. SOLUTION: The cable connecting member 1 for use in cold climates includes an EP rubber insulating tube 10 accommodating the end of a cable 20, a tapered insulating plug 11 provided in the rubber insulating tube 10, an EP rubber inner-semiconducting layer 101 mounted substantially vertical to the axial direction of the insulating plug 11 inside the rubber insulating tube 10 for accommodating the tip of the cable 20, and a silicone rubber spacer 15 inserted between the end of the rubber insulating tube 10 and the cable 20. At a temperature at which the tensile modulus of the rubber insulating tube 10 increases three or more times as high as the tensile modulus of the rubber insulating tube 10 at room temperature, the tensile modulus of the rubber spacer 15 at such temperature is less than three times as high as the tensile modulus of the rubber spacer at room temperature.
