A bayonet connector (112, 128) suitable, in use, for connecting a filter cartridge (72) or an air supply tube to a respirator (10, 14), the bayonet connector (112) comprising a male part (112) and a female part, the male part comprising a tube (114) having at least two radially- extending lugs (130, 132) formed on its outer sidewall adapted to engage with first and second engaging ribs (136, 138) located on an interior sidewall of the female part (128). Alternatively, the female part may comprise a tube having at least two inwardly radially-extending lugs formed on its inner sidewall adapted to engage with first and second engaging ribs located on an exterior sidewall of the male part. In both cases, the bayonet connector (112, 128) is characterised by the radially-extending lugs (130, 132) and the engaging ribs (136, 138) being located at different axial positions. |
