In an incandescent mantle formed of a woven fabric tube and having at least one open end with a fireproof attaching material provided for attaching at least one of the ends of the tube to a burner or to a shaped part for a burner of an incandescent lamp, the improvement comprising:
- engaged upon at least one open end of the mantle, on at least a side facing the burner or the shaped part for the burner, at least one additional fireproof material portion in the form of a flexible thread is provided between the burner and mantle when said mantle is in an attached state engaged with said burner;
- said thread in the attached state is passed around the circumference of the fabric tube in at least one location forming a loop;
- said attaching material is routed not to penetrate the fabric tube;
- and
- said thread being routed to wind around the attaching material in at least one place, preferably winding around the inside, thereby imparting to the mantle increased mechanical stability with respect to the burner as a result.
