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.

A clamp comprising: a pair of flexible and relatively inextensible sheet-metal strips each having a pair of strip ends and normally formed into an annulus with one strip end of one strip spaced angularly from one strip end of the other strip and each other strip end lying against the inner face of the other strip intermediate the strip ends thereof; a sheet-metal buckle on said other end of each of said strips and having a pair of bend-over ends embracing and slidably receiving the other strip intermediate said strip ends thereof; means for drawing said one strip ends angularly together and, when said strips are snugly fitted around an object to be clamped, thereby pressing each of said buckles tightly against said object and locking each of said buckles to the strip normally slidable therein.
