Abstract
The clamping collar has a belt (10) looped back onto itself and having two ends provided with lugs (12, 14) that are upstanding and that are suitable for being brought closer together for tightening the collar. The collar has a spacer (22) having a land (24) extending between the ends (10A, 10B) of the belt (10), and a web (26) having at least a first tab that is upstanding relative to said land, which web extends between the lugs. The spacer is formed by a strip that is folded between a first fold at the junction between the first tab and the land (24) and a second fold situated at a first end of the land, the land having a first double- walled portion between the first and second folds.
