An electric connection device for a housing element of the housing has at least one external electric connection element on the housing element for connecting a supply line of the internal electric device to an external electric device outside the housing. At least one line section, electrically connected to the external electric connection element on one side, and at least one terminal element, connected to the line section on the other side, connect to the supply line of the internal electric device. The external electric connection element, the at line section, and the terminal element are fixed on the housing element, and the terminal element is an inner face of the housing element and accessible from an outer face in a vicinity of an assembly opening in the housing element. ## Claims ### Claim at position 1 1-10. (canceled) ### Claim 11 An electrical connecting device for a housing element of a housing and for an internal electrical device arranged in the housing, the connecting device comprising: at least one external electrical connecting element disposed on the housing element for connecting at least one supply line of the internal electrical device to at least one external electrical device outside the housing; at least one line section having a first end electrically connected to said at least one external electrical connecting element; each of said at least one external electrical connecting element, said at least one line section, and said at least one connector element being fixedly disposed on the housing element; at least one connector element disposed inside the housing element in a region of at least one assembly opening formed in the housing element so as to be accessible from an outside of the housing; and said at least one line section further having a second end, distal from said first end, electrically connected to said at least one connector element for connecting to the at least one supply line of the internal electrical device. ### Claim 12 (depends on 11) The electrical connecting device according to claim 11, wherein the housing is configured to contain a traction battery. ### Claim 13 (depends on 11) The electrical connecting device according to claim 11, wherein the housing is configured to contain a traction battery for an electrically operable vehicle. ### Claim 14 (depends on 11) The electrical connecting device according to claim 11, wherein said at least one connector element that is connected to said at least one line section is directly connected to the at least one supply line of the internal electrical device. ### Claim 15 (depends on 14) The electrical connecting device according to claim 14, wherein said at least one connector element is directly connected to the at least one supply line by way of a plug and/or screw connection. ### Claim 16 (depends on 11) The electrical connecting device according to claim 11, which comprises at least one holding element fastening said at least one line section to said housing element. ### Claim 17 (depends on 11) The electrical connecting device according to claim 11, wherein said at least one line section is integrally formed in a material of said housing element. ### Claim 18 (depends on 17) The electrical connecting device according to claim 17, wherein said at least one line section is embedded in and/or injection molded into a plastic material of said housing element. ### Claim 19 (depends on 11) The electrical connecting device according to claim 11, wherein said at least one assembly opening in said housing element is a closable opening. ### Claim 20 (depends on 11) The electrical connecting device according to claim 11, which comprises a closing element for closing said opening with a fluid-tight seal. ### Claim 21 (depends on 11) The electrical connecting device according to claim 11, which further comprises at least one holding device for holding at least said at least one connector element projecting through said at least one assembly opening in the housing element to the outside of the housing for assembling said housing element on a remainder of the housing. ### Claim 22 (depends on 11) The electrical connecting device according to claim 11, wherein said at least one external electrical connecting element arranged on said housing element is configured for detachable connection to the at least one external electrical device arranged outside the housing. ### Claim 23 (depends on 11) The electrical connecting device according to claim 11, wherein detachable connection with the at least one external electrical device arranged outside the housing is a pluggable connection. ### Claim 24 A housing element with an electrical connecting device for an internal electrical device arranged in a housing, the housing element comprising: at least one external electrical connecting element disposed on the housing element for connecting at least one supply line of the internal electrical device to at least one external electrical device outside the housing;
