Abstract
The planar abutment key (11) incorporates in its body portion (18) two flexible fingers (22) extending laterally and angularly in the direction away from the end portion (19) of the key which forms abutment arms (21) for the plunger, each finger (22) ending in a sharp angle (24), the transverse distance at rest between the sharp angles (24) being greater than the transverse width (d.sub.1) of the slot (12) in the hub portion of the assistance piston (1) in which the key (11) is housed.
