A circumferential clamp (2) including a clamping band (4) having oppositely disposed circumferential ends (8, 10) and a latching assembly (6) for securing the ends (8, 10) together. The latching assembly (6) includes first and second latching devices (12, 14), each of which includes an elongate element (16, 26, 28) which is pivotably mounted on the clamping band (4) adjacent one of the ends (8, 10) and is engageable with the clamping band (4) adjacent the other end to latch the ends (8, 10) together. The lengthwise axes of the elongate elements (16, 26, 28) lie in, or intersect, a common plane tangential to the clamping band (4), and may be coincident with, or intersect, each other.
