The invention relates to an electrical connection arrangement (4) for the electrical and mechanical connection of a first electrical conductor (2) to a second electrical conductor (3), having an electrical connection element (8) with a first end and with a second end, wherein a press portion (9) is arranged at the first end, the press portion having at least one lateral contact surface (11) for electrical contact with an inner lateral surface (12) of a contact recess (13) of the first electrical conductor (2), and wherein a bearing portion (10) is arranged at the second end, the bearing portion having a bearing surface (14) for non-positive connection to a side surface (15) of the second electrical conductor (3). A connection bore (16) extends at least between the bearing portion (10) and the press portion (9) so that the connection element (8) can receive a first fastening means (17) or forms a first fastening means (17) itself, and can receive a second fastening means (18) which can be connected to the first fastening means (17) so that the non-positive connection is produced between the bearing surface (14) of the bearing portion (10) and the side surface (15) of the second electrical conductor (3). It is provided that the press portion (9) can be radially spread apart by the first fastening means (17) and/or by the second fastening means (18) in order to bring about a non-positive connection between the at least one lateral contact surface (11) and the inner lateral surface (12) of the contact recess (13), by the two fastening means (17, 18) being connected together.
