An implement for tying up and suspending objects comprising an elongate strap made of semi rigid plastic material that includes a first end and a second end, and an inner side and an outer side; said elongated strap further including in said inner side, a plurality of teeth, equally spaced and transversely disposed with respect to a longitudinal direction of said elongated strap; a plurality of grooves alternating with said plurality of teeth; each tooth of said plurality of teeth has in cross-section a triangular shape and each groove of said plurality of grooves has a shape and size to correspond with each tooth of said plurality of teeth; said plurality of teeth extending from said first end up to a first no-tooth recessed zone located in proximity of said second end, a group of several teeth alternating with a group of several grooves following after said recessed zone, characterized in that said inner side further incorporates a second no-tooth recessed zone located after said group of several teeth and after said group of several grooves; and in that it comprises a buckle made of rigid plastic material, and used to interlock with said elongated strap; wherein the second end incorporates a suspending fixture; said elongated strap, laterally, at each side of said plurality of teeth and said plurality of grooves, starting from bottoms of said plurality of teeth and said plurality of grooves, is provided with an ascending slanted zone, followed by a flat zone, parallel to said elongated strap, then by an externally directed descending slanted zone and, finally, terminates into a straight zone perpendicular to said elongated strap; said outer side incorporating an internal stop projecting from the outer side beyond an overall thickness of said elongated strap and ending into a first contact surface ('a') perpendicular to said elongated strap; said first contact surface ("a") being so positioned on said outer side as to correspond to the beginning of said group of teeth situated on said inner side; said outer side incorporating as well an external stop ("b") disposed close to an extremity of said second end and projecting from the outer side, beyond said overall thickness of said elongated strap and ending into a second contact surface ("b") perpendicular to said elongated strap, first and second contact surfaces ("a", "b") being parallel; a first indented retaining zone starting from first said contact surface ("a") of said internal stop and, lengthwise, having such a dimension that enables said buckle to be lodged there, when said implement is in a final closed position; a second indented retaining zone starting from said second contact surface ("b") of said external stop and, lengthwise, having such a dimension that enables said buckle to be lodged there during a tying up of said implement; an indented transition-intermediary zone,slightly wider than said first and second indented retaining zones being interposed between the former and the latter, so that said buckle is kept in place, either in said first indented retaining zone or in said second indented zone, no hand being necessary therefor; for moving said buckle from said first indented retaining zone to said second indented retaining zone or vice versa, a slight manual effort to move said buckle along said indented transition-intermediary is needed; and said buckle having a shape of a rectangular parallelepiped that incorporates a cavity delimited by a top, a bottom, lateral sides, an entrance and an exit for a passage of said first end or said second end, or both.
