Abstract: A fastener-forming element, designed to fasten at least one oblong element, e.g. at least one electric cable, to a second element, e.g. a panel or a partition, e.g. of a motor vehicle, is characterized in that it is constituted by a strip having two opposite faces, male elements in particular in the form of hooks, projecting from one of the two faces, said male elements being designed to co-operate either with female elements, in particular loops, stemming from the second element (when a male-female self-fastener is formed), or with other male elements stemming from the second element (when a male-male self-fastener is formed), and in that the strip is rolled up helically, so that said one of the two faces from which the male elements stem is on the outside of the fastener-forming element, the strip thus defining an inside space designed to receive the at least one element of oblong shape.
