A tamper-proof locking device mountable on a lidded container or the like. A first member has a first portion which overlies the closed lid of the container. A second portion of the first member overlies a side wall of the container below the lid. A third portion of the first member extends away from the second portion and the container side wall. An opening in the third portion has an axis which is perpendicular to the plane of the lid. The second portion is secured to the side wall of the container. The second member has a first portion which cooperates with the first member when assembled thereon to form an enclosure that prevents access of a tool to the element which secures the second portion of the first member to the container side wall. The second member has a second portion which is parallel to the third portion of the first member and which has an opening. This opening is in alignment with the opening in the third section of the first member. A rectilinear shackle is receivable in the openings. The shackle includes a projection which extends and underlies the third portion of the first member.
