element 3 at an angle in the distal direction the activator element is in a relaxed state in the initial position but can be flexibly deflected outwardly in the radial direction toward the drive element axis during preparation of the administering device they provide different functions for controlling the sequence of individual preparation steps in conjunction with the drive element they may be thought of and or referred to as the control mechanism for the sequence control fig1 b shows a detailed view of the proximal region of the administering device illustrated in fig1 a in which the device has been rotated by 90 u00b0 a lock element 10 may be seen which co operates with a projection 11 on the housing 1 together the lock element 10 and projection 11 constitute a clamp connection to secure the lock element 3 in addition to the locking action provided by the contact between the retaining element 6 and housing projection 9 and the contact between the drive button 8 and housing projection 9 the contact between the retaining element 6 and the housing projection 9 in the axial direction affords a blocking action against a movement of the drive element in the proximal.
