wherein:
at least one first fixing or locking element, which is designed to fix a first one of the connecting plugs to the housing, is formed on an interior of the wall within the connection area;
at least one second fixing or locking element, which is designed to fix a second one of the connecting plugs to the housing, is formed on an exterior of the wall;
the wall defines a generally rectangular shaped receiving contour and includes at least two wall sections parallel to each other;
the at least one first fixing or locking element includes a section on each of the two parallel wall sections; and
the at least one second fixing or locking element includes a section on each of the two parallel wall sections.
6. The electrical device as recited in claim 1 , wherein the at least one first fixing or locking element is designed differently than the at least one second fixing or locking element.
7. The electrical device as recited in claim 1 , wherein the at least one first fixing or locking element and the at least one second fixing or locking element each has a respective recess for a formfitting accommodation of a respective counter element of a respective one of the connecting plugs.
8. An electrical device comprising:
a housing;
a wall that is formed on an exterior surface of the housing, extends away from the exterior surface of the housing to an end of the wall, and circumferentially surrounds a connection area;
electrical connecting elements in the connection area within the wall and extending longitudinally away from the surface of the housing to respective ends configured for alternatively mating with corresponding respective electrical connecting elements of a plurality of connecting plugs that are each alternatively pluggable onto or into the wall in a direction from the end of the wall towards the surface of the housing, to thereby provide an electrical connection between the electrical device and the connecting plug;
wherein:
at least one first fixing or locking element, which is designed to fix a first one of the connecting plugs to the housing, is formed on an interior of the wall within the connection area;
at least one second fixing or locking element, which is designed to fix a second one of the connecting plugs to the housing, is formed on an exterior of the wall;
the at least one first fixing or locking element includes a first pair of elements situated on respective areas of the wall that are directly opposite each other and face each other; and
the at least one second fixing or locking element includes a second pair of elements situated on respective areas of the wall that are directly opposite each other and face away from each other.
9. A connection arrangement, comprising:
a first connecting plug; and
an electrical device that includes:
a housing;
a single wall that is formed on an exterior surface of the housing, extends away from the exterior surface of the housing to an end of the single wall, and circumferentially surrounds a connection area;
electrical connecting elements in the connection area within the single wall and extending longitudinally away from the surface of the housing to respective ends configured for alternatively mating with corresponding respective electrical connecting elements of (a) the first connecting plug and (b) a second connecting plug, each of the first and second connecting plugs being alternatively pluggable onto or into the single wall in a direction from the end of the single wall towards the surface of the housing, to thereby provide an electrical connection between the electrical device and the respective connecting plug;
wherein:
at least one first fixing or locking element, which is designed to fix one of the first and the second connecting plugs to the housing by preventing withdrawal of the one of the first and second connecting plugs from the housing in a direction from the surface of the housing towards the end of the single wall, is formed on an interior surface of the single wall within the connection area, and at least one second fixing or locking element, which is designed to fix the other of the first and second connecting plugs to the housing by preventing withdrawal of the other of the first and second connecting plugs from the housing in the direction from the surface of the housing towards the end of the single wall, is formed on an exterior surface of the single wall; and
