A method for producing a composite profile, wherein two or more partial profiles (2.1 - 2.n) are connected with each other by adhesive bonding on surfaces of the partial profiles (2.1 - 2.n) abutting each another to form the composite profile; wherein - two or more partial profiles (2.1 - 2.n) are each additionally connected with each other on surfaces (20.1 - 20.n) of the partial profiles (2.1 - 2.n) abutting each another by at least two interacting plug connection elements (3, 4); - for this purpose at least one first plug connection element is produced as a tab or tongue that is formed out of the surface (20.1 - 20.n) of the one partial profile (2.1 - 2.n) or that is connected with the surface (20.1 - 20.n) of the one partial profile (2.1 - 2.n) and at least one second plug connection element is produced as an opening attached in the surface (20.1 - 20.n) of the other partial profile (2.1 - 2.n); - the partial profiles (2.1 - 2.n) are placed on top of each other in a position relative to each other, in which the tab or tongue of the one partial profile (2.1 - 2.n) is received in the opening of the other partial profile (2.1 - 2.n); and - the two partial profiles (2.1 - 2.n) are displaced relative to each other in a displacement direction facing in tab or tongue direction in the plane of the surfaces (20.1 - 20.n) abutting each other, provided with an adhesive on one or both sides, and thus the tab or tongue of the one partial profile (2.1 - 2.n) is across an edge of the opening of the other partial profile (2.1 - 2.n) brought into holding engagement with the partial profile (2.1 - 2.n) including the opening and thereby the partial profiles (2.1 - 2.n) are fixed in the correct position against each other for a hardening of the adhesive, wherein individual or all pairs of first and second plug connection elements (3, 4) are each assigned with a push-back lock, and said/each push-back lock is shaped, preferably punched, as a locking gill that is each adjacent to the tab or tongue and interacting with the associated opening, characterized in that the locking gill is shaped such that it is facing obliquely upwards in a direction opposite the displacement direction from the surface of the second partial profile (2.2). - two or more partial profiles (2.1 - 2.n) are each additionally connected with each other on surfaces (20.1 - 20.n) of the partial profiles (2.1 - 2.n) abutting each another by at least two interacting plug connection elements (3, 4); - for this purpose at least one first plug connection element is produced as a tab or tongue that is formed out of the surface (20.1 - 20.n) of the one partial profile (2.1 - 2.n) or that is connected with the surface (20.1 - 20.n) of the one partial profile (2.1 - 2.n) and at least one second plug connection element is produced as an opening attached in the surface (20.1 - 20.n) of the other partial profile (2.1 - 2.n); - the partial profiles (2.1 - 2.n) are placed on top of each other in a position relative to each other, in which the tab or tongue of the one partial profile (2.1 - 2.n) is received in the opening of the other partial profile (2.1 - 2.n); and - the two partial profiles (2.1 - 2.n) are displaced relative to each other in a displacement direction facing in tab or tongue direction in the plane of the surfaces (20.1 - 20.n) abutting each other, provided with an adhesive on one or both sides, and thus the tab or tongue of the one partial profile (2.1 - 2.n) is across an edge of the opening of the other partial profile (2.1 - 2.n) brought into holding engagement with the partial profile (2.1 - 2.n) including the opening and thereby the partial profiles (2.1 - 2.n) are fixed in the correct position against each other for a hardening of the adhesive, wherein individual or all pairs of first and second plug connection elements (3, 4) are each assigned with a push-back lock, and said/each push-back lock is shaped, preferably punched, as a locking gill that is each adjacent to the tab or tongue and interacting with the associated opening,
