摘要：
The invention relates to an administration device for administering an injectable product. Said device comprises a housing containing a reservoir for the product, a plunger that is located in the reservoir so that it can be displaced in a feed direction, a plunger rod that can be displaced in the feed direction and that acts on the plunger and a locking mechanism that prevents the displacement of the plunger rod against the feed direction. The locking mechanism comprises or consists of a first locking device, formed by the plunger rod and a second locking device that cannot be displaced in relation to the housing against the feed direction, said two devices being permanently engaged with one another. Preferably, in addition, the second locking device cannot be displaced in relation to the housing in the feed direction.
