A secondary securing arrangement (19,28,29,30) for securing a first component (11) to a second component (13) when primary securing means (17) is inadvertently removed, said first component (11) including an outwardly extending spigot (12) slidably engaging said secondary securing means (19, 28,29,30) and to which said second component (13) is assembled and secured by said primary securing means (17). The arrangement is such that if in use said primary securing means (17) is inadvertently removed, said secondary securing means (19, 28, 29, 30) insures limited axial displacement but no separation of said second component (13) from said first component (11). <IMAGE> |
