1. An injector for transcutaneously introducing a sensor into a patient, the injector comprising:
a cannula,
a sensor arranged in the cannula,
a base element,
a sliding element arranged displaceably on the base element in an injection direction,
a slot at least in a proximal region of the cannula, the slot extending in a longitudinal direction of the cannula, and
a holding element on the base element and engaged in the cannula through the slot and against a distal end of the sensor, wherein
at least one of the holding element or the base element have at least one fixing arrangement, wherein the fixing arrangement is configured to automatically lock the holding element on the base element,
the sliding element is adapted for transcutaneously introducing the cannula having the sensor into the patient in an injection operation,
the holding element is arranged displaceably on the base element such that when pulling the cannula out of the patient in an ejection operation, the holding element prevents the sensor from being pulled out, and
the holding element and the sensor are separable units and configured such that when the cannula, the base element, the sliding element, and the holding element are removed from the patient in a removal operation, the sensor remains in the patient.
