Joining system for mechanically joining two materials

A receiving device for receiving a pin for mechanically joining two materials, wherein the receiving device has an elongate shape formed along an axis of extension, the receiving device comprising:

• a barb arrangement, at a front end, for anchoring the receiving device in a bore in a material, wherein the barb arrangement has a main body, surrounding the axis of extension, and has spreading elements protruding radially from the main body, the spreading elements being configured to, when the barb arrangement is pressed into the bore, exert a hooking effect to inhibit release of the barb arrangement from the bore;
• and
• a sleeve for receiving the pin, the sleeve surrounding the axis of extension, connected to the barb arrangement, and accessible from a rear end located opposite the front end,
• wherein the sleeve has a biasing arrangement for biasing the pin in a direction of the front end, wherein the sleeve is configured such that:
• the biasing arrangement has a spring element extending with a rounded shape in a circumferential direction, the spring element being configured as part of a clamping cone,
• wherein the spring element extends in the circumferential direction only over a partial circumference and is configured to interact with a belly region of the pin;
• when the pin is inserted, the spring element is configured to push against the pin with a force acting radially relative to the axis of extension, wherein the spring element is configured to cause the force to act on the belly region and to provide the force over a biasing section on the pin;
• the spring element is configured to interact with the belly region to generate an axial force along the axis of extension towards the front end on the pin;
• and
• in response to the axial force, the pin is pushed into the sleeve along the axis of extension towards the front end within a section on the sleeve that corresponds to the biasing section on the pin when the pin is inserted,
• wherein the spring element is configured to cooperate with an edge face of an edge of the pin,
• wherein the spring element and the edge are configured to enable the pin to be inserted into the sleeve in the direction of the front end but, by cooperating with the edge, to inhibit the pin from being pulled out in a direction of the rear end,
• wherein a normal to the edge face is oriented parallel to the axis of extension,
• wherein the spring element has a contacting region with an edge face counterpart for butting against the edge face, wherein a normal to the edge face counterpart is oriented parallel to the axis of extension, and
• wherein the spring element has a further contacting region for contacting the belly region of the pin and pushing radially against the belly region when the pin is inserted in the sleeve, wherein the further contacting region is adjacent to the edge face counterpart and a normal to the further contacting region is oriented perpendicular to the axis of extension.
