A heat-recoverable article for protecting a conduit, for example, an electric cable, where its conductors pass through an aperture in a bulkhead, in order, for example, to prevent chafing; the article has an inner expansible and an outer shrinkable sleeve, the outer jacket of the cable terminating in an annular space between the sleeves, the space shrinking on heating of the article; one end of the inner sleeve is expansible to grip the bulkhead.
