摘要 A process for making a connecting element, made of a hard material and provided with a jagged external wall, integral with one end of a flexible member having at least one armoring consisting of metallic wires, comprising the steps of covering said connecting element with an anchoring sleeve made of a material of lower hardness than that of the material constituting the armoring and said element, laying the armoring onto said anchoring ring, covering the armoring with a compression sleeve of lower hardness than that of the armoring and drawing the assembly of the connecting element, the armoring and said compression ring through a die, thereby producing through a great reduction in the diameter of said compression ring, a penetration of said armoring into said anchoring ring and into said compression ring and at the same time an inlaying of the material forming said anchoring ring between the jags of said jagged external wall of the connecting element.
