(57) A seal (102) is suitable for use with a sealable product which includes a fastener
and a sealing device for securing said fastener. Said sealing device (102) comprises
a locking housing having a lock opening with shoulders at each side thereof, a tab
cover connected to the fastener and engageable with the locking housing. The seal
(102) comprises: a head (104), and a pair of parallel inner legs (106), separated
by a channel (124). Each inner leg (106) includes a first, wide portion (112) adjacent
said head and narrowing on an outer edge distal said channel to form a second (126),
narrow portion. An outer leg extends from an end the inner leg, distal said first
wide portion, the outer leg extends away from said channel and towards said first
wide portion. The outer leg is resiliently deformable towards said narrow portion
of said inner leg, and includes at an end proximal to, and extending outside of a
width of, said wide portion of said inner leg, a surface, positioned for latching
engagement behind a respective said shoulder. The seal (102) is characterised in that
said first wide portion of each inner leg includes a region of weakness (119) which
is selectively fracturable and in that each of said pair of inner legs is resiliently
deformable into said channel.
