FIELD: locking systems.
SUBSTANCE: invention relates to a locking device for locking a pipe. The locking device (2) has a central axis (8) and a bearing element (4), at least one sealing contact surface (6) and at least one drive device with at least one mounting element (10), shifted relative to the bearing element (4) from the first position to the second position, in which the locking device (2) is in the sealing position, and the mounting element (10) is installed with the possibility of rotation relative to the bearing element (4) around the drive axis (12), whose inclination to the central axis (8) of the locking device does not exceed 10°, moreover, the drive device includes an eccentric element (14) rotated around the drive axis (12) and having a sliding surface (16) facing away from the drive axis (12), located at a variable distance from the drive axis (12), the development of a simple and quickly mounted locking element with the most technologically reliable seal.
EFFECT: invention offers a simple and quickly mounted locking element with a technologically reliable seal.
