The attachment means 12 includes a bracket 26 shaped and dimensioned to be releasably attachable to a part of the closing mechanism 14 of the container. In the embodiment shown in the drawings, the bracket 26 is a U-bracket and includes two arms 28 and a base 30.
Furthermore, the arms 28 of the bracket 26 define apertures 32 for receiving at least a part of a shank 34 there through. The arms 20 of the bracket 26 are configured to allow for releasable attachment to the elongate portion 16 of the closing mechanism 14 of the container in that the arms 20 are configured to be compressible towards one another so as to allow for releasable attachment to elongate portion 16 of the closing mechanism 14 of the container.
The attachment means 12 includes a shank 34 receivable through the apertures 32 defined by the arms 28 of the bracket 26, wherein the bracket 26 is rendered releasably attachable to elongate portion 16 of the closing mechanism 14 when the shank 34 is passed through the apertures 32.
The shank 34 is a generally cylindrical elongate includes a tapered end 36, and a thread that has a first threaded section 38 and a second counter- threaded section 40. The first threaded section 38 has a larger diameter relative the second counter-threaded section 40.
The shank 34 includes a head 42, the head 42 being in the form of a stamp plate. The head 42 is shaped and dimensioned to limit the path of the shank 34 through the apertures 32 defined by the arm 28 of the bracket 26.

In the embodiment shown in Figure 4, the first nut 48 and the second nut 50 define further apertures 60 and 62, respectively for receiving retaining pins (not shown).
Any one or more of these further apertures 60 and 62 are threaded. Is to be appreciated from this specification that the retaining pin can be any one or more from the group of a screw, bolt, dowel pins, castellated nut and cotter pin arrangement and the like.
In the embodiment shown in the Figure 4, the second nut 48 defines an aperture 63 for receiving further retaining means. The further retaining means may be in the form of a security seal (not shown).
The channel 20 includes a first open end 66 and a second closed end 68 and typically includes an extension 70 at the first open end 66. The extension 70 defines an aperture 72 for receiving the shank 34.
The extension 70 defines a surface 74 configured to abut a part of the elongate member 16 of the closing mechanism 14 of the container.
The apertures 72 and 32 defined by the extension 70 and the arm 28 of the bracket 26 receive the shank 34 simultaneously, rendering the bracket 26 attachable to the extension 70 of the channel 20.
The channel 20 has raised sides 76 and defines apertures 78 for receiving an anti-sliding pin 80 that are frictionally engagable with at least a part of the elongate portion 16 of the closing mechanism 14. The frictional engagement serves to minimise movement of the locking device 10 along the long axis 24 of the elongate member 16 whilst in locked position.
The second closed end 68 of the channel 20 includes a hook 22.
The hook 22 is engagable with the end zone 18 of the closing mechanism 14 of the container. When in engaged position the hook 22 discourages the rotation of the closing mechanism 14 around its long axis 24. It is to be appreciated from the specification that the bracket 26 can be rotated around a long axis 45 of the shank 34, thereby providing for optimal positioning of the bracket 26 and to provide further frictional engagement with the closing mechanism 14 of the container.
