The present invention relates to a re-usable clamp constituted by a wound over strap of metal and comprising, near to the two ends of the strap, two radial folds or lugs projecting externally from the strap, the first of said lugs extending into a portion which follows the periphery of the clamp to constitute a sole-plate extending at least over the distance separating the two lugs, whereas the second lug is also provided with an extension which is substantially parallel to the periphery of the clamp and situated at a distance therefrom which is nearly equal to the height of one lug; the sole-plate extending from the first lug is provided with at least one asperity projecting externally from the strap and designed to cooperate, when the clamp is in a closed but untightened position, with the bearing part of a recess correspondingly provided in the strap behind the second lug.
