    摘要： In forming an air tight dam at a connecting zone of two communication cables or an opened zone of a cable sheath, slit spring sleeves capable of compressing the sheath and the insulated conductor body are inserted in an outer sleeve which covers the connecting zone or the opened zone of the sheath. The slit spring sleeves are first inserted into the outer sleeve while maintained in the enlarged state. A room-temperature setting resin exhibiting rubber-like elasticity after setting is poured to fill the slit spring sleeves and to set therein. Then, the means for enlarging the slit spring sleeves is released to compress the interior of the dam.
