A fastening with a first composite part, the part is secured, near an attachment zone, to a second part, a bearing edge of the part contacts a bearing edge of the second part. The fastening attaches the first part to the second part. Near the attachment zone, the first part is composed by a drape made of a superposition of unidirectional layers with angles of orientation of fibers that are different between two adjacent layers. Near the attachment zone, at least one cavity is laid out in the first part, parallel to the contact surface and along a direction perpendicular to the direction of the unidirectional layers, and at least one hole perpendicular to the contact surface, where the hole starts from its bearing edge and opens in the cavity, and receives a threaded element.
