Abstract
Abstract The invention relates to an article suitable for making an electrical connection between two electrical conductors, for example an earth conductor and the outer conductor of a coaxial cable. The article comprises a heat-shrinkable sleeve and a quantity of solder which is positioned eccentrically within the sleeve and is held by and/or on the sleeve. The sleeve also comprises or has guide means capable of locating a portion of the earth conductor in proximity to the quantity of solder. On shrinking of the sleeve and fusing of the solder, an electrical connection can be made between an earth conductor received in the guide means and the outer conductor of a coaxial cable received in the sleeve.
