FIELD: machine engineering.

SUBSTANCE: shrinking clamping ring from the initially open clamping belt for closing is equipped with ends interlocking like a puzzle. From one end of the belt there is a tongue protruding in the longitudinal direction of the belt, and on this tongue there are fingerlike elements disposed transversely to the longitudinal direction of the tape; from the other end of the belt a notch is made, which in its configuration complements the shape of the tongue.
