摘要：
The invention relates to a plunger rod (1) to be connected to a plunger stopper (100), comprising :
- A rod (2),
- A sleeve (9) having a movable part (16) capable of moving from a first radial position to a second radial position under the effect of a centrifugal force applied thereon,
- Said rod (2) being capable of sliding in translation within said sleeve (9) from a first axial position to a second axial position under the effect of a distal pressure exerted on its proximal end (3),
- Releasable locking means (7, 14) configured for temporary locking said rod (2) in its second axial position.
The invention also relates to a method for connecting/disconnecting the plunger rod and a plunger stopper.
