LOCKING DEVICE

FIELD: construction industry. ^ SUBSTANCE: invention refers to hardware. Locking device consists of rope piece, one end of which being passive is fixed in the casing, and the other free end passes through end-to-end channel in the casing during locking, and is fixed in it with locking mechanism made in the form of rotary element separated in the section with undersised cross section, and threaded section following it and located in threaded casing hole made perpendicular to end-to-end channel axis; at that the latter is provided with blind plugged hole. Plug is installed from end-to-end channel side, and is provided with longitudinal groove on one side, which crosses end-to-end channel and is symmetrically located relative to its axis, and on the other side it is provided with central through-hole wherein lock member with unsmooth face is installed so that it can move lengthwise. Lock member contacts the rope piece when rotary element is being screwed in. Longitudinal axis of lock member coincides with longitudinal axis of nut which serves as a threaded hole and which is located before plug in blind hole and is fixed in it mainly by means of folding. Lock member is made in the form of a pin and installed in a central through-hole fit for it, which prevents pin from falling out. ^ EFFECT: improving locking device reliability. ^ 15 cl, 8 dwg
