FIELD: hardware devices. SUBSTANCE: lock has body, locking mechanism with turning cylinder installed in opening of body, latch located in guide members of body, and latch interlocking mechanism consisting of latch movement limiter, stop, actuator, and spring detent of stop. Latch movement limiter is made in the form of strip attached at inner side to body and with its plane located above latch surface. Stop is in the form of bar with bent-in flange installed on side surface of latch with possibility for reciprocal lateral displacement when its flange is located above latch surface at side of limiter location. Used as latch interlocking mechanism is lug of turning cylinder which for this purpose is kept in contact with bent-in end of stop end face. At other side of lock, used as stop actuator is fixing handle of lock rigidly connected by axle through hole in body cover with surface of stop bar. Spring detent of latch interlocking mechanism is installed on side surface of latch and it presses stop flange to its upper surface by action of spring upon axle of fixing handle. For convenient fastening to body, limiter can be made in the form of angle attached to lock body. Guide members of stop can be slotted in lock body. Coaxially with guide members at side of turning cylinder position, latch can have lateral slot for bent-in end of lug to act upon stop end face and upon latch at closing and opening of lock. EFFECT: simple design and reduced cost to manufacture. 3 cl, 4 dwg
