An insulation-piercing fastener (1) has a generally cylindrical shank. The e nd portion of the shank which, in use, engages an insulated electrical conducto r is formed with a hollowed end portion. The hollowed end portion may form par t of a bore (2) extending through the shank. The wall of the hollowed end portion has at least one interruption (3), and more preferably a pair of diametrically opposed interruptions (3) which together define a slot extendi ng across the end portion of the fastener (1).
