CLAIMS
1. Crimp barrel (1) for an electric contact member (5) with at least one conductor receptacle (11) extending along a conductor direction (13) and with two crimp wings (19) extending perpendicular to the conductor direction (13) for closing of the conductor receptacle (11), characterized in that the conductor receptacle (11) comprises at least one retaining aperture (23) through which at least one plug portion (25) of at least one crimp wing (19) protrudes in a closed State (21) of the conductor receptacle (11).
2. Crimp barrel (1) according to Claim 1, characterized in that the at least one plug portion (25) is formed by a projection (27) extending away from the residual crimp wing (1) perpendicularly to the conductor direction (13).
3. Crimp barrel (1) according to Claim 1 or 2, characterized in that in the closed State (21), each crimp wing (19) protrudes through the at least one retaining aperture (23) with at least one plug portion (25).
4. Crimp barrel (1) according to any one of Claims 1 to 3, characterized in that in conductor direction (13) the at least one plug portion (25) of a crimp wing (19) is arranged at the same height as the at least one plug portion (25) of the other crimp wing (19).
5. Crimp barrel (1) according to any one of Claims 1 to 4, characterized in that the conductor receptacle (11) comprises at least one common retaining aperture (23) for two plug portions (25).
6. Crimp barrel (1) according to any one of Claims 1 to 5, characterized in that the at least one retaining aperture (23) is arranged centered between the both crimp wings (19).
7. Crimp barrel (1) according to any one of Claims 1 to 6, characterized in that in the closed State (21) the at least one plug portion (25) is bent and flatly abuts an outside (53) of the conductor receptacle (11).
8. Crimp barrel (1) according to any one of Claims 1 to 7, characterized in that an outside (53) of the conductor receptacle (11) is provided with at least one depression (55) for at least section-wise receiving the at least one plug portion (25).
9. Crimp barrel (1) according to any one of Claims 1 to 8, characterized in that at least one plug portion (25) is provided with at least one locking member (57) extending away from the residual plug portion (25) in conductor direction (13).

10. Crimp barrel (1) according to any one of Claims 1 to 9, characterized in that in the area of the at least one retaining aperture (23) the conductor receptacle (11) is provided with at least one guiding member (59) for guiding of the at least one plug portion (25) during closing of the conductor receptacle (11).
11. Crimp barrel (1) according to any one of Claims 1 to 10, characterized in that the at least one retaining aperture (23) and the at least one plug portion (25) are arranged at a contact side end (31) of the conductor receptacle (11), which contact side end (31) is located opposite a conductor side end (29).
12. Electric contact member (5) for connection with at least one electric conductor (15), characterized in that the contact member (5) is provided with at least one crimp barrel (1) according to any one of Claims 1 to 11.
13. Electric contact member (5) according to Claim 12, characterized in that the crimp barrel (1) is formed monolithically with the residual contact member (5).
14. Electric contact member (5) according to Claim 12 or 13, characterized in that the electric contact member (5) is formed as a stamped bent part (7).
15. Tool (39) for closing of a crimp barrel (1) according to any one of Claims 1 to 11, in particular an anvil (41), wherein the tool (39) comprises a receptacle (43) at which a bottom (17) of the crimp barrel (1) may abut, characterized in that the receptacle (43) comprises at least one depression (51) for receiving and deforming of at least one plug portion (25).
