Abstract
A joining element to be anchored in an object with the aid of a thermoplastic material and mechanical vibration includes a proximal end and a distal end that are spaced from one another along an axis of the joining element. A contact face is in the area of the proximal end, the contact face being suitable for being contacted with a vibrating tool for applying, to the joining element, mechanical vibration and a force parallel to the axis. The wall anchoring portion is situated between the proximal end and the distal end, and has a circumferential surface being equipped with a plurality of recesses and radially protruding energy concentrating elements between the recesses. A tubular portion is situated between the proximal end and the distal end and extends distally from the wall anchoring portion.
