Asensor assembly (256) for detecting at least one analyte in a body fluid and a method of mounting a sensor (110) for detecting at least one analyte in a body fluid to a body mount (212) attachable to a body of a user are disclosed. The sensor assembly (256) comprises: -at least one sensor (110), wherein the sensor (110) is an electrochemical sensor； -at least one body mount (212) configured for attachment to a body of a user； -at least one insertion element (236) for transferring the sensor (110) to the body mount (212)； -at least one first adhesive element (248) attached to one or both of the body mount (212) or the sensor (110), configured for attaching the sensor (110) to the body mount (212)； -at least one second adhesive element (250) attached to one or both of the sensor (110) or the insertion element (236), configured for releasably attaching the sensor (110) to the insertion element (236), wherein the insertion element (236) is configured to transfer the sensor (110) from an initial position, in which the sensor (110) is attached to the insertion element (236) via the second adhesive element (250), into a final position in which the sensor (110) is attached to the body mount (212) via the first adhesive element (248) and released from the insertion element (236).
