Clamp

Claim 1

Re-usable clamp, comprising a wound metal strap having two ends, said strap having two radial lugs projecting externally from the strap at respective ends thereof, 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, the second lug is formed with an extension arranged substantially parallel to the periphery of the clamp and situated at a distance therefrom nearly equal to the height of one lug, said extension of the second lug being provided with a short hooked portion having a free end constituting a clamping member for fastening over the first lug in a tightened position of the clamp, said sole-plate including an extending part extending from the first lug and having at least one asperity projecting externally from an end of said extending part to cooperate with a bearing element of a recess correspondingly formed in the strap behind the second lug, wherein the asperity in said extending part is spaced from said first lug by a length greater than the length from the extension of the second lug to the bearing element of said recess behind the second lug, whereby when said clamp is in a closed but untightened position said asperity engages said bearing element of said recess and when said clamp is in said tightened position said asperity does not engage said bearing element of said recess.
