A ring clamp has a pair of flexible sheet-metal strips formed into a ring with one end of each strip juxtaposed with the one end of the other strip, and the other end of each strip lying intermediate the ends of the other strips. The buckles are each formed of a pair of sheet-metal parts one of which has ends bent over and formed with channels into which fit similar channels of another latch part whose ends are in turn bent over the first part for locking-together of the entire buckle into a rigid unit without the use of welding or rivets. Furthermore each buckle has inwardly directed teeth that can bite into the object being clamped. When the ends of the clamp are drawn together to tighten it around an object the two buckles are tightly pressed against the object and prevent sliding of the two strips relative to each other. |
