The apparatus comprises a plunger (13) designed to slide in a front portion (11) of the apparatus acting as a plug guide, for driving a plug and sealing it, then to be returned rearwardly to the firing position, with balls (18) for braking the plunger (13) which are mounted in recesses of the plug guide (11). By cooperation with the plunger (13), the balls (18) are driven radially towards the plunger (13) upon application of the apparatus and rearward sliding of the plug guide (11).
