In a safety lock for a container connection (3) at least two cams (9, 10) are arranged on the contacting surfaces of the container connection pieces (4) and locking piece (5) and cooperate with a radially open circumferential groove (7) and with at least two grooves (6 and 8) having parallel axes on the respective counterpart (5 or 4), in the manner of a bayonet catch. In order to obtain a safety lock system with a plurality of safe combination pairs which can absolutely not be interchanged, the combination pairs of several cams (9 and 10) and axially parallel grooves (6 and 8) in the circumferential direction of the container connection piece (4) and locking piece (5) have mutually different circumferential sizes (angular spacings) (X1) in several container connections (3) of the same type. |
