Fastening member of the tightening band type constituted by a tape whose two ends comprise complementary attachment means, each of the ends comprising on the other hand a prehension means enabling the tightening and cooperation of the fastening means with the aid of a suitable tool in the form of pliers, one of the ends of the tape having at least one zone of smaller transverse section constituting a zone of least resistance.
A fastening member of the tightening band type comprising an elongated tape having opposed first and second end portions and a generally uniform transverse cross-sectional area between said end portions except at said first end portion whereby said tape has substantially the same strength to resist stress all along its length, said first and second end portions including free ends and having complementary cooperating attachment means formed thereon inwardly of said free ends for holding said end portions together in any of a plurality of relative positions, said first and second end portions each also including prehension means for cooperating with a tightening tool to enable said first and second end portions to be moved with respect to each other in adjacent relation thereby to engage said cooperating attachment means in a desired relative position, said first end portion of the tape having at least one zone of smaller cross-sectional area than the remainder of the tape defining a zone of least resistance whose strength to resist stress is less than that of the remainder of the tape and being located between the attachment means and the prehension means of said first end portion of the tape.
A fastening member of the tightening band type comprising an elongated tape having opposed first and second end portions and a substantially uniform width and thickness along its entire length except at a predetermined zone in said first end portion whereby said tape has substantially the same strength to resist stress all along its length except at said zone, said first and second end portions including free ends and having complementary cooperating attachment means formed thereon inwardly of said free ends for holding said end portions together in any of a plurality of relative positions, said first and second end portions each also including prehension means for cooperating with a tightening tool to enable said first and second end portions to be moved with respect to each other in adjacent relation thereby to engage said cooperating attachment means in a desired relative position, said first end portion of the tape at said zone being smaller in at least one of its width and thickness dimensions than the remainder of the tape to define a zone of least resistance whose strength to resist stress is less than that of the remainder of the tape, said zone being located between the attachment means and the prehension means of said first end portion of the tape.

The present invention relates to a fastening member of the tightening band type.
Numerous types of tightening bands are already known, which are used in particular in the manufacture of electrical household apparatus or in the automobile industry, for example for ensuring the tight connection of two pipes, of which one is made of supple material. Bands are known in particular which are constituted by a tape element made of supple material, e.g. metal, wound on itself. The ends of such a band have at least on their opposite faces complementary attachment means, for example suitably orientated teeth. These ends are generally maintained in contact with each other by a clip or the like enabling the band to be maintained tightened.
This type of fastening member is generally placed in position by means of special pliers or the like whose jaws cooperate with prehension means provided on the band near its ends, or more simply pull on the non-covered end of the band after it has been wound, whilst preventing it from sliding on the object to be tightened, by any suitable means.
The invention will be more readily understood on reading the following description with reference to the accompanying drawings, in which:
FIG. 1, 2 and 3 show plan views of three variant embodiments of tightening bands in accordance with the invention.
Referring now to the drawings, the Figures show a band which is essentially constituted by a flat tape 1, for example made of metal, of constant width. Each of its ends 1a and 1b has toothed zones 2 and 3 intended for cooperation with each other after the tape has been wound on the object to be tightened. If necessary, the teeth are held in mesh by a clip or the like (not shown) generally placed in position before tightening.
Behind the toothed zone 2, with respect to the corresponding end 1a, there is provided at least one rough surface 9, for example stamped, constituting a point of support for one of the jaws of a tightening tool such as, for example, the pliers like tool shown in U.S. Pat. No. 3,293,709. The other jaw will cooperate with the end 1b corresponding to the toothed zone 3 under conditions which will be described hereinbelow.
Between the end 1b and the toothed zone 3 which is located on the visible surface of tape 1, there is provided a plane part constituting an element that may be gripped by the tightening tool.
