Claim 9:
10. The capping machine according to claim 9, wherein said safety locking device comprises a peg protruding axially from the lower face of the compression box and engaging said at least one movable engagement element at a slot made on said movable engagement element, said peg having an axial base portion of a larger diameter than an axial tip portion;
wherein said slot is shaped to allow relative sliding between said movable engagement element and the axial tip portion of said peg during movement of said movable engagement element between said unlocking position and said locking position, said slot being engageable by the axial base portion of said peg only at an enlarged section of said slot which the peg meets only when said movable engagement element is in said locking position; and
wherein said peg is axially movable with respect to said compression box to move between:
a position of minimum projection, wherein said peg protrudes from the lower face of said compression box only with the axial tip portion, and
a position of maximum projection, wherein said peg protrudes from the lower face of said compression box and with the axial base portion,
said peg being subjected to thrust of elastic means tending to push said peg axially towards said position of maximum projection so that, when said peg meets the enlarged section of said slot, said peg engages said slot with the axial base portion, thereby firmly locking said movable engagement element in the locking position.
