FIELD: construction.
SUBSTANCE: flexible LSD comprises a body 1 and a rope section 2, one end of which is rigidly fixed in a dead hole 3 of a body. The free end of the rope section is equipped with a rigidly fixed conical tip 4, is pulled via a through channel 5 arranged in the body and is fixed by means of a fixation mechanism 6 arranged in the body. The fixation mechanism comprises fixing elements arranged in the form of spring-loaded balls or rolls. In the body there is a stepped hole 7 with the following components serially arranged in it: a unit of fixation of a tip of a free end of a rope section with the help of any of elastic elements 8, 13 or 14 and/or a unit of protection against nondestructive opening of the LSD. The LSD comprises a capsule 9 with a substance capable of hardening outside the capsule, and a piston 10 installed in front of the capsule at the side of the entry into the stepped hole.
EFFECT: improved operational properties of a flexible LSD due to provision of reliable fixation of a tip of a free end of a rope and protection of an LSD against nondestructive opening.
