Abstract
The buckle of the invention provides a secure and essentially irreversible means for securing parts of the straps, ideally about compressed inbaled material and/or baled material that is prone to shrinkage. The clip (1) comprises a single component that can easily and quickly be applied by hand and associated strapping maybe re-tensioned as appropriate without removing the clip or straps from or about the baled material. The clip is made to rotate about approximately 180°, whereby forces at a resilient nose portion (8A, 8B) of a gripping member (4A, 4B) are caused to clamp down on a part of a strap.
Claims18
A buckle:
- incorporating separate spaced-apart strap-securing means through each of which, in use, a strap end can be threaded and then be pulled through the buckle to tighten the buckled strap progressively around an outside object;
- each of strap securing means comprising a pair of opposed gripping members or jaws between which a respective strap end can be passed and around which an adjacent region of a remainder of a respective strap end can then be looped in a manner which will allow a respective strap end to slide against one another as the strap is pulled through the buckle;
- and with each such pair of jaws being laterally offset relative to each other in such a way so that resulting forces acting on the buckle, after the strap is tightened, create a turning moment urging the buckle to rotate through substantially 180° about a generally centrally positioned axis thereby frictionally trapping a respective strap end in the buckle.

- and with each such pair of jaws being offset relative to each other in such a way so that resulting forces acting on the buckle after the strap is tightened, create a turning moment urging the buckle to rotate through substantially 180° thereby frictionally trapping a respective strap end in the buckle;
- and
- a suitably positioned recess partially separates at least one of the jaws of each pair from an adjacent region of the buckle and in which at least one additional recess if formed in at least one of the jaws.
