Clamp having joggles

A clamping collar comprising a metal belt, two spaced-apart tightening lugs connected to the belt and suitable for being brought towards each other in order to tighten the collar, and a bridging plate that co-operates with the belt to bridge the gap between the lugs, the belt including an overlap portion that carries the first tightening lug and that has its inside face provided with a setback into which a first end of the plate penetrates during tightening of the collar, said

• setback being defined by a first joggle having an end wall that forms two surfaces on either side of a longitudinal midline of the belt, which surfaces are disposed substantially symmetrically about said midline, and are inclined both relative to a longitudinal direction and relative to a transverse direction of the belt, and each of which surfaces extends over a substantial fraction of the half-width of the belt.
