Abstract: This invention relates to a securing mechanism in the form of a clamp, said securing mechanism also incorporating a locking mechanism which when in locked form prevents the clamp from being readily opened. In preferred embodiments the securing mechanism is in the form of a clamp comprising at least two retaining members, a translation means associated with the two retaining members, a handle containing a locking mechanism attached to said translation means, characterised in that the handle can be moved by the translation means to secure the retaining members with respect to each other, and when the locking mechanism is activated on the handle ready movement of the handle and subsequent release of the retaining members is prevented. The securing mechanism provides a secure means by which valuable articles can be held.
