1. A fusible link (100) for installation in a through opening (4) of a gas tank (1000), the fusible link (100) having a tension rod (1), a guide sleeve (2) with at least one fluid guide duct (2a) that guides gas out of the gas tank (1000) into the surroundings of the gas tank (1000), and a fusible sheath (3),
wherein the guide sleeve (2) surrounds the tension rod (1) in an at least partially annular fashion and the fusible sheath (3) encloses the guide sleeve (2) at least partially,
wherein the tension rod (1) has a tapered section (1a) that tapers away from the gas tank (1000), the guide sleeve (2) has at least one predetermined breaking section (2b) configured such that the at least one predetermined breaking section (2b) breaks when the fusible link (100) is installed in the through opening (4) such that fusible material (3a) is introduced into the at least one fluid guide duct (2a) and penetrates at least partially into the at least one fluid guide duct (2a) and blocks a flow of gas through the at least one fluid guide duct (2a), and the tension rod (1) and the guide sleeve (2) have a greater strength and/or temperature resistance than the fusible material (3a).
