1. A fuse, comprising:
at least one fuse blade, formed in a sheet having two opposite main faces extending along a longitudinal axis of the fuse blade, each fuse blade comprising a portion in which is formed a reduced section defining a transverse plane to the fuse blade; and
two connection terminals, each terminal being connected to each fuse blade, arc guards, made of a preformed elastic material, which are associated in pairs, the arc guards of the same pair being each located opposite one another on one main respective side of the same fuse blade, wherein:
for at least a first pair of arc guards, an adhesive layer is interposed between the fuse blade and an internal face of each arc guard of this pair, the internal face being oriented towards one of the main faces of the fuse blade, so as to fix each arc guard on the fuse blade, and
the adhesive layer is made of a material that is of a different grade or of a different type from the elastic material of the arc guards.
