FASTENING CONSTRUCTION, EXTERIOR VISION UNIT OF A MOTOR VEHICLE AND METHOD FOR ASSEMBLING OR DISASSEMBLING A FASTENING CONSTRUCTION

The invention proposes a fastening construction comprising a base part fixedly connectable to a vehicle, a locking element, a spring, and a positioning element. The base part comprises a shaft having an axial contact element extending axially. The spring is configured to surround the outer radial surface of the shaft and be compressed axially. The positioning element comprises a first portion configured to engage and position a first axial end of the spring relative to the shaft, and a second portion configured to cooperate with a second contact portion of the locking element in the axial direction. The locking element comprises a first contact portion configured to cooperate with the axial contact element of the shaft, and a second contact portion inclined radially outward and/or inward to transmit a force of the spring acting on the positioning element to bias the locking element against the axial contact element.
