Abstract
A relocking mechanism for a safe or like security closure comprises one or more relocking devices mounted on a panel of the closure rearwardly of the main bolt and operable to prevent retraction of the bolt. Each of the relocking devices includes a mounting plate carrying a pair of unidirectional hinges constituted by roller clutches, a plate-like bolt-engaging member being connected to the hinges for uni-directional pivotal movement from a disengaging position to bolt-engaging position. The bolt-engaging member is resiliently biassed towards the bolt-engaging position but is normally retained in the disengaging position by a control element which releases the member in the event of forcible attack on the closure.
