1. A closure for nozzles with heat activation, comprising:
a nozzle body (1); and
an outlet channel (11), wherein a seal (4) is arranged on the nozzle body (1) above the outlet channel (11), which seals off the outlet channel (11), wherein the seal (4) is pressed against the outlet channel (11) by a cover (5) and is held in a closed position, blocking the outlet channel (11), wherein the cover (5) is detachably fastened to the nozzle body (1) and can be actively or passively removed in the event of fire, the cover (5) is arranged in the nozzle body (1) and connected to the nozzle body (1) by at least two fastenings, a first fastening of the at least two fastenings is a releasable arrangement (6) and a second fastening of the at least two fastenings is a connection (7) around which the cover (5) is movable, wherein the releasable arrangement (6) comprises a heat-sensitive element, which is frangible glass bulb (64), and is released upon active or passive activation of the heat-sensitive element, wherein the heat-sensitive element is arranged offset from a center of the cover (5), wherein the releasable arrangement (6) includes a latch (65) movable in the cover (5) between two positions: a closed position of the latch in which a front end of the latch (65) engages in a first recess (12) of the nozzle body (1) or abuts against a first abutment of the nozzle body (1), and an open position in which the front end of the latch (65) does not engage in the first recess (12) or does not abut against the first abutment, and wherein the cover (5) includes a spring, a magnet or a weight acting as an actuating element (66) which acts on the latch (65) and on the cover (5) in such a way that the latch (65) is always pushed or pulled towards the open position, wherein in a waiting position, the glass bulb (64) holds the latch (65) in the closed position against the force of the actuating element (66).

8. A closure for nozzles with heat activation, comprising:
a nozzle body (1); and
an outlet channel (11), wherein a seal (4) is arranged on the nozzle body (1) above the outlet channel (11), which seals off the outlet channel (11), wherein the seal (4) is pressed against the outlet channel (11) by a cover (5) and is held in a closed position, blocking the outlet channel (11), wherein the cover (5) is detachably fastened to the nozzle body (1) and can be actively or passively removed in the event of fire, the cover (5) is arranged in the nozzle body (1) and connected to the nozzle body (1) by at least two fastenings, a first fastening of the at least two fastenings is a releasable arrangement (6) and a second fastening of the at least two fastenings is a connection (7) around which the cover (5) is movable, wherein the releasable arrangement (6) comprises a heat-sensitive element, which is frangible glass bulb (64), and is released upon active or passive activation of the heat-sensitive element, wherein the heat-sensitive element is arranged inside the nozzle body (1) and either located inside the cover (5) or on the inside of the cover (5), facing the outlet channel (11) and active heating of the heat-sensitive element is controlled by an intelligent controller, which communicates with one or more fire sensors (14), both the intelligent controller and the one or more fire sensors (14) are arranged in or on the nozzle body, wherein the releasable arrangement (6) includes a latch (65) movable in the cover (5) between two positions: a closed position of the latch in which a front end of the latch (65) engages in a first recess (12) of the nozzle body (1) or abuts against a first abutment of the nozzle body (1), and an open position in which the front end of the latch (65) does not engage in the first recess (12) or does not abut against the first abutment, and wherein the cover (5) includes a spring, a magnet or a weight acting as an actuating element (66) which acts on the latch (65) and on the cover (5) in such a way that the latch (65) is always pushed or pulled towards the open position, wherein in a waiting position, the glass bulb (64) holds the latch (65) in the closed position against the force of the actuating element (66).
