An electric fuse rendered fluid-tight by means of a single piece sleeve of a heat-shrinkable and heat-shrunk substance. The sleeve covers the cylindrical casing of the fuse and the lateral surfaces of cylindrical coaxial extensions of terminal plugs of the fuse having substantially the same diameter as the inner diameter of the casing. The portions of the sleeve overlapping the lateral surfaces of the aforementioned extensions are clamped against said surfaces by annular metal clamps which are provided with adjustment or clamping screws.
