Methods for joining insulated condutors used in treating a subsurface formation are described herein. A method for coupling ends of two insulated conductors includes coupling an end portion of a core of a first insulated conductor to an end portion of a core of a second insulated conductor placing electrically insulating material over exposed portions of the cores; placing a sleeve over end portions of the two insulated conductors to be coupled, the sleeve comprising one or more raised portions in which the end portions comprise the exposed portions of the cores; coupling the sleeve to jackets of the insulated conductors; and mechanically compressing the raised portions of the sleeve until the raised portions of the sleeve have a diameter substantially similar to a remainder of the sleeve in which the compression of the raised portions of the sleeve compacts the electrically insulating material inside the sleeve.
