Abstract

Electrical connections to line substrates, such as cables, are made by employing a radially shrinkable coil member which is positioned about the substrate in an expanded form and is then caused or allowed to revert to a smaller radius so that it grips the substrate. In preferred embodiments the coil member is made from a heat-recoverable material or is made from a resilient material which is held in an expanded form by a disburdenable material, e.g. a fusible material such as solder, which is subsequently removed, deformed or destroyed so as to cause connection. The devices are especially suitable for connecting earth leads to the sheaths of mineral insulated cables in the vicinity of terminations and splices thereof.
