An over-centre closing device for fixing together the first and the second parts of an article, comprising a holder pivotally attached to a lever which is pivotally mounted to the first part of the article, the holder having an engagement surface which engages the second part of the article and fastens the two parts of the article together when the holder is over the centre line. The holder has an extension which extends beyond the engagement surface and which may cooperate with the second part of the article to provide initial closing leverage during an initial stage of closing the article and which ensures the engagement surface to contact the second part of the article to provide final closing leverage during a final stage of closing the article. |
