The fire collar includes a body (11) that is constructed from a flexible, elongate strip of steel (12) having a first end portion (13) associated with one end thereof and an opposing second end portion (14) associated with the opposite end thereof. The fire collar (10) also includes actuation means, including a plurality of torsion springs (28) manufactured from spring steel, such as spring steel having a diameter of 4 mm or 5 mm. Each torsion spring (28) includes a spring body (29) comprising one or more helical coils, and two tails, (30) and (31), that extend outwardly away from opposite ends of the body.
