Abstract
The coder device prevents plugs being assembled to a counter-plug device having a different coding. The coder device is formed by tongue-like projections on a plug and by corresponding chamber-like recesses on the counter-plug device. The projections are provided with a theoretical breakage point and can be broken off. The broken off projections can be inserted into the associated recess of the housing of the counter-plug device. By breaking off projections in different combinations, it is possible to individualize the original universal coder device.
