A fire extinguisher safety mechanism (4) comprises a release member (16) and an indicator member (18). The release member (16) is configured for lengthwise insertion and withdrawal from between the handles (8, 10) of a fire extinguisher (2). It has a proximal end (38) for gripping by a user and a distal end (46) having an aperture (56). The indicator member (18) has a head (60) and a shank (62) projecting from the head (60). The distal end (80) of the shank has resilient retaining teeth (84). The indicator member (18) is configured to be mounted to the extinguisher 2 with its shank (62) passing through an aperture (71) in the extinguisher (2) and through the aperture (56) in the distal end (46) of the release member (16) so as to be retained relative to the release member (16) by said resilient retaining teeth and to prevent accidental withdrawal of the release member (16) from between the handles (8, 10). An indicator member comprising a disc-like head portion and a shank extending thereof, where the shank comprises a weaker intermediate region (92), is also disclosed.
