Abstract
The present invention relates to a system for locking a dosing button in a device for the administration of a product to be injected in predetermined doses.

The button ensures the transport of the selected dose when it is displaced from a first position into a second by actuating the drive member (5, 7). The dose is selected in the first position by rotating the dosing button (9) so that is can be moved from a first rotation position indicating that no transport is possible into a second rotation position. This device further comprises a first indicator sleeve (15) affixed to the body as well as a second indicator sleeve (17) capable of rotation together with the dosing button (9), wherein both sleeves include indication members (16, 18) for reading the selected dose according to the r…
