Abstract: A plastic fastening strap for holding a plurality of elongated objects having a holding part with a locking projection and a flexible tightening band having a plurality of spaced transverse crossbars. After the band is wrapped around the objects, it is snapped onto the projection and locked in place. To facilitate hooking and unhooking of the band while at the same time preventing accidental unhooking, the locking projection has a downwardly extending notch for engaging and holding a crossbar of the band and a thickness forward of the notch that is approximately 10% larger than the longitudinal distance between two adjacent crossbars.
