Abstract A device particularly for locking a calculator to a mounting base comprises a U-shape stirrup which is secured to the bottom of the device such as by epoxy glue and which includes a reinforcing rod therethrough so that it cannot be easily severed. The complete locking device includes a bar member having a hook shaped end which engages over the stirrup in an unreleasable manner and a securement end which extends beyond the end of the device being secured so that it cannot be pivoted out of this stirrup. The securement end is secured by a securing screw which extends through a locking device comprising a first member which engages through the securing plate to the mounting base and a threaded screw which extends through the first member and engages into the mounting base and has a head portion which is covered within the first member. A second member is telescoped in respect to the first member and it includes a locking cylinder which is key operated to engage a latch into a receiving groove of the first member to lock the two members together and prevent access to the screw head.
A device for locking an article to a mounting base comprising a U-shaped stirrup connected to the bottom of the article to be secured and which defines an opening between the bottom thereof and the bottom of the article, a securing plate extending through the opening of the stirrup and having an end bent downwardly on the interior side of said stirrup preventing removal of said plate by passage of the bent end through the opening, the opposite end of said plate extending beyond the edge of the article and having a securement opening, a threaded securement member extended through the opening and secured in the mounting base and a locking device engaged over the threaded securement member and preventing access thereto.
