The invention relates to a device (1) comprising at least one welding cam (2-2") for attaching ballistic protection elements (10) and additional add-on parts (11) to an object (5). In order to be able to attach a ballistic protection element (10) and an add-on part (11) to the same welding cam (2-2") with different torques, a welding cam (2-2") having a threaded bore (3) and an external thread (4) is proposed. In this case, the ballistic protection element (10) is screwed on with a first predefinable torque by means of a clamping nut (7; 7') which can be screwed onto the external thread (4) of the welding cam (2-2"). For this purpose, the clamping nut (7; 7') has a through-bore with an internal thread (8). Through this through-bore, the corresponding add-on part (11) can be connected to the threaded bore (3) of the welding cam (2-2"). Since the add-on part (11) bears against the clamping nut (7; 7') and not against the ballistic protection element (10), the add-on part (11) can be attached to the welding cam (2-2") with a second torque conforming to standards, without damaging the ballistic protection element (10). |
