Abstract
A clamping collar constituted by a rolled-up first metal strip portion referred to as an "inner" portion and having two radial folds in the vicinity of one of its ends forming a "lug", and by a second strip portion referred to as an "outer" portion, which is fixed at its first end to the outside face of the inner portion, which has an undulation forming a reserve of resilience, which is provided at its second end with a hook suitable for engaging behind the lug while the collar is being clamped, and which includes an "intermediate" part situated between the undulation and the hook and extending substantially along the periphery of the inner portion which thus has a covered zone covered by said intermediate part. The collar includes first and second abutment means formed respectively on the intermediate part of the outer portion and on the covered zone of the inner portion and suitable for co-operating with each other to set a limit on use of the reserve of resilience.
