Cable ties were originally designed to be able to fix, for example, cables arranged in cable harnesses of aircraft in a simple manner to each other. Prior to the invention of the cable tie, it was common that the individual cables of a cable harness were tied or tied by means of a technically demanding process with wire or wax tape. Today, cable ties are a widely used connection element for provisionally or permanently fixing cables, hoses or the like to a laying site, for example.

Both in the private sector, as well as in a variety of professional fields of application, for example in mechanical engineering, in the electrical industry, but also in the construction industry, cable ties are used to solve a variety of design problems. Due to the very wide application spectrum of cable ties, these have been developed into a variety of embodiments.

Despite the great variety of cable ties for a wide variety of applications, the known embodiments of cable ties still have some serious shortcomings. A variety of cable ties have a straight cable strap that must be bent by a user before the cable strap can be passed through the head of the cable tie. In order for a correct locking can be done, the cable band must be bent in a certain direction in a majority of the known cable ties, otherwise no locking means can be brought into operative connection with the locking side of the cable band. However, due to the external design of the known cable ties, it is often difficult for the user to know in which direction the cable strap must be correctly bent, so that a multiplicity of cable ties are first incorrectly bent by the users and no correct locking can take place.

Another disadvantage of the known cable ties is that they are not optimized for one-handed operation. In particular, when using cable ties in hard to reach places, such as in cable ducts or server cabinets, the use of known from the prior art cable ties usually requires their handling with two hands and always a high degree of instinct and / or experience.

It is therefore considered an object of the present invention to provide a cable tie whose operation is simplified and which also allows one-handed use.

This object is achieved in that the cable band has a curvature, wherein the band end of the cable band is spaced by the curvature of a maximum of 20 mm, preferably not more than 10 mm and more preferably not more than 5 mm from an insertion opening of the recess, one at the end of the tape Tapes to the cable band applied tangent is directed towards the insertion, so that is pressed by compressing the curved cable strip of the insertion of the cable strip between the contact surface and the locking means in the recess and wherein the cable tie by further compression of the cable strap and thereby effected in Active connection bring the locking side with the locking means can be locked. It is envisaged that in the cable tie according to the invention by the curvature of the cable band of the insertion portion is arranged and aligned to the insertion opening such that upon compression of the cable band of the insertion is inserted into the insertion opening. In order to be able to adapt the cable tie to different uses, it is also possible and provided according to the invention for the cable strap to have a multiplicity of different curved shapes, for example that of a substantially circular loop. Moreover, it is also possible and provided that the shape of the loop can be adapted to be encompassed by the loop and by the cable tie to be determined objects, such as cables of a cable bundle, such as by the cable strap an outer contour of the objects is reshaped.

The invention takes advantage of the finding that the commercially available cable ties are not designed with regard to their shape to be used as simply as possible. Most cable ties have a flat cable strap, which must first be bent, and then usually with two hands to thread the free end of the cable strap into the insertion opening on the cable head. A use of such cable ties in inaccessible places or in connection with objects that must be held or positioned during the desired attachment with a cable tie, thereby considerably more difficult, so that the costs incurred for the installation is relatively high and attachment of the cable tie sometimes even with two hands can not be done easily. Even those cable ties that have a curved cable band, often do not facilitate the insertion of the free end of the cable band in the insertion opening on the cable head and can not easily be mounted easily.

In order to facilitate the use and installation of a cable tie according to the invention above all provided that the cable band is so curved and aligned in the free end of the tape so that the tape end has only a small distance to the insertion in the cable head and a compression of the the curved cable band shaped and almost closed loop the tape end is almost automatically pressed into the insertion of the cable head and can be defined therein. In this way, a particularly simple operation of the cable tie is made possible, often the cable tie can be held with one hand and then first compressed and then tightened.

For the design of the locking means and the contact surface different variants and configurations are conceivable. The abutment surface can in turn also have a blocking means and the cable band can be configured on opposite sides so that the band end of the cable band can be inserted in any orientation into the insertion opening and fixed therein. Nevertheless, the cable band is expediently shaped such that the band end is introduced into the insertion opening with an orientation advantageous for the desired blocking effect if the band end is displaced in the direction of the insertion opening.

The cable tie according to the invention allows a particularly simple and rapid installation of the cable tie to set, for example, an object such as a cable to a cable harness or cable cabinet or to attach a large-sized poster on a mast. In many cases, by a suitable specification of a size or curvature of the cable band and a one-handed use and determination of the cable tie can be made possible. This greatly facilitates the use of the cable tie in inaccessible places or in connection with large or heavy objects.

Regardless of the shape of the cable strap, it is provided according to the invention that the strap end is located a maximum of 20 mm from the insertion opening when the cable tie is unloaded and not locked. In order to enable the simplest possible operation of the cable tie according to the invention, it is provided that a distance between the tape end and the insertion opening should be as small as possible. Depending on the intended use of the cable tie, it may also be appropriate that a use-dependent minimum distance between the tape end and the insertion is not exceeded, for example, to have sufficient clearance when positioning the cable tie, so that a risk of accidental locking of the cable tie is reduced , Overall, it is achieved by such a configuration of the cable tie according to the invention that the cable tie after a pre-positioning, for example, around a zusammenzubindendes cable bundle, one-handed lockable.
