Abstract: A locking device for a plug-in connection between a fluid pipe, provided with a shaped-on radially protruding abutment, and a connecting part utilizes a clamp, which can be guided in the connecting part, two branches of the clamp overlapping the abutment of a correctly plugged-in fluid pipe in order to secure the plug-in connection against axial separation. A guide slot, for receiving the clamp, opens along its length towards a plug-in side of the connecting part in order to prevent incorrectly produced plug-in connections, i.e. unsecured conditions, while the clamp itself is provided with a guard which can be displaced in the elongated opening of the guide slot. This guard ensures that the abutment of the plugged-in fluid pipe is either overlapped by the clamp branches, in the case of a correct plug-in connection, or remains visible above the plug-in side of the connecting part, in the case of an incorrectly executed plug-in connection.
