Abstract: The present invention relates to reusable bundle tie devices, comprising a strap (1) with transversal knurl teeth (11), associated with an enclosement buckle with an upper top (4) elevated from the strap leading end (2) by a solid state side wall (3), forming a longitudinal channel (12) and aperture for transversal docking and undocking of the strap middle part by cross slipping over the tooth unit (7). The enclosement flap (6) linked to the leading end (2) by flexible state reduced portion (5) locks the buckle by means of one top latch between two cam locks (19 and 20) contiguous to each stopper (13 and 14) and one bottom latch between two cam locks (17 and 18) that replace the flexible portion (5) during enclosement. This enclosement buckle is opposite to the tail end (8), comprising a suspension hook (9) or slot (10).
