Protection device with fuses for medium-voltage overhead electrical networks, especially for the power supply to voltage step-down transformers, characterised in that the set of fuses (9) is mounted within an insulating casing (6) which is closed and sealed by two terminal capsules (7) provided with a blind tubular end part (7a) oriented axially for clamping the ends of a flexible overhead tapping (4), one of the said capsules being equipped with a visual detection element (18, 20) which is held in position clipped against elastic means by a fuse wire (16) which a removable pin (15) links to an internal conductor (10) joining the two capsules together. <IMAGE>
