A method for manufacturing a regeneratively cooled nozzle extension of a rocket combustion chamber, the nozzle extension including a first wall and a second wall arranged coaxially to each other and between which a number of cooling channels is configured that are laterally delimited by cooling channel webs. The first wall and the second wall are connected to each other by a positive fit by cooling channel webs of the first wall engaging with corresponding recesses of the second wall for forming the positive fit. The positive fit is produced by a forming process in the region of the cooling channels of the second wall having the recesses.
