description A device for dosed administration of an injectable product, comprising: a) a housing (1; 2; 30) provided with a reservoir (23) for the product; b) at least one drive member (3, 4) provided with a piston (26), which forces a product out of the reservoir (23) through an outlet (25) by displacement of the piston in a direction of advancement, and c) a drive knob (5) which displaces the drive member (3,4) in relation to the housing (1; 2; 30) when actuated; d) at least one delaying element (11) which can be displaced from a first position into a second position which is distanced from the first position by actutating the drive knob (5) in relation to the drive member (3, 4) in the longitudinal direction of the device, said drive member (3, 4) remaining in a rest position in relation to the housing (1; 2; 30); wherein e) the at least one delaying member (11) produces a contact in the first or second position with the drive member (3, 4) in such a way that when the drive knob (5) is actuated, the drive member (3, 4) can be displaced in the direction of advancement before or after the at least one delaying member(11) is displaced in relation to the drive member (3, 4).
