A cartridge type fuse having a casing. A pair of terminal plugs is press-fitted into the ends of said casing and conductively interconnected by a fusible element. Each of said pair of terminal plugs has a knurled lateral wall. A pair of annular fasteners is mounted on said casing each adjacent one of the ends thereof. Said fasteners press the wall of said casing radially inwardly into firm engagement with said knurled lateral walls of said pair of terminal plugs. The casing preferably includes an outermost ply of woven glass cloth, an innermost ply of woven glass cloth, and at least one intermediate ply of relatively loose non-woven fibers sandwiched between said outermost ply and said innermost ply, and the constituent plies of said casing are preferably integrated by polyester resin.
