1. Device for attaching an object to a support element and/or for stabilizing the support element, wherein the device comprises a condition monitoring for determining a deformation, the device comprising
an attachment body with an attachment portion for inserting in the support element,
a conductor trace which is electrically conductive and applied along a trace-shaped extension for measuring a mechanical tension at the attachment portion,
wherein the attachment body comprises a coupling portion for coupling with an evaluation unit,
wherein the conductor trace is configured such that it is suppliable with electric energy from the coupling portion,
wherein the electrical resistance of the conductor trace is indicative for the deformation of the attachment body in the attachment portion.
