LOCKING DEVICE Russian patent published in 2009 - IPC E05B39/02 G09F3/00 

FIELD: construction.

SUBSTANCE: invention concerns fixture and locking device. Device includes case with through hole, exit channel crossed by reference hole for passive and loose ends of cable section respectively, and stopping element with base and conical parts, mounted so as to be shifted by compelling force impact, for interaction with cable section. Stopping element in reference hole can perform straight line movement, and force impact is applied by external load. Reference hole is dead-end and stepped, with smaller step overrunning exit channel. Stopping element with collar is sprung and mounted in reference hole by bearing sleeve. In position prepared for locking, base part is partially protruding out of case. To lock the device, an external load should be applied at the end of stopping element, which shifts inside the case, its sharp end going through cable section in stopping zone.

EFFECT: enhanced reliability of locking (stopping), prevented unauthorised opening without visible destruction traces.
