FIELD: mechanical engineering; locking devices. SUBSTANCE: proposed invention relates to locking devices arranged over center lines, in particular, to casings such as casings of cable joint covers, or component part of casing proper, or part of clamping device for fixing first and second parts of casing. Over- center locking device for joining first and second parts of article has handle hinge-connected with lever hinge-mounted on first part of article. Handle has catching surface engaging with second part of article and fixing indicated two parts of article together when handle in arranged in position over center line. Handle has elongated end passing over catching surface and made for free engagement with second part of article to form primary closing leverage at primary stage of article closing. Elongated end of handle provides bringing of catching surface in contact with second part of article to form final closing leverage at final stage of article closing. EFFECT: enhanced reliability of locking. 7 cl, 4 dwg
