HOSE CLAMP Russian patent published in 2012 - IPC F16L33/25 

FIELD: machine building.

SUBSTANCE: connection of two ends of the tape is done by a guide hook located on the internal side of the tape and inserted into a socket designed for the guide hook and located on the external side of the tape and a locking hook also located on the internal side of the tape and inserted into the socket designed for the locking hook and located on the external side of the tape. The socket designed for the locking hook is a depressed pocket achieved by cold pressing of a metal strip, and forming a unified whole with it around its perimetre. The internal surface of the socket is perpendicular to the tape surface in the support area adjacent to the outer end of the tape. The locking hook has a projection directed to the side opposite to the internal end of the tape, which when the hose clamp is pulled engages its sheared edge with the support area of the socket designed for a locking hook.

EFFECT: due to the fact that its design is integral with the metal strip, the socket for the locking hook has a much greater strength.
