Abstract: A connection device or distribution equipment for electrical installation equipment, which can be built into installation equipment, preferably a household distribution box, in which the electrical connection between two bus bars (21, 31) built into a household distribution box (10) is produced by an electrical line connector (40) which runs in the interspace between the two base housings (20, 30) containing the bus bars (21, 31) and the back wall (11) of the household distribution box (10). Connection contact pieces (42a, 42b, 42c) are provided at both ends of the line connector (40), and can be brought into engagement by vertical introduction into the plug sockets (13) located on the upper edges (23, 33) of the base housings (20, 30), whereby the electrical contact is produced between the first bus bar (21) and the second bus bar (31).
