Abstract
The collar has a metal belt (10), a pair of projecting lugs (12, 14), a tightening rod (16) disposed in holes in the lugs, and tightening members (16A, 16B) co-operating with the rod and with bearing portions of the lugs. At least one of the lugs in the pair is a lug (14) having an extension, the bearing portion of which lug is formed in an extension (17) of the lug, which extension is folded over towards the rear of the lug, and is provided with a hole for the tightening rod. The extension (17) and the front portion (15) of the lug (14) having an extension are interconnected via a strip portion (20) forming a link loop defining an axial tunnel having its two axial ends open, the tunnel being shaped so that the angle of inclination between the extension (17) and the front portion (15) of the lug can change when the collar is tightened.
