TUNNEL LINING ELEMENT

The invention relates to a tunnel lining element (10) comprising at least two tunnel lining segments (11), with a body (20), the tunnel lining segment (11) comprising two opposing short sides (17) at which the at least two tunnel lining segments (11) are interconnected such that the tunnel lining element (10) is a closed element. According to the invention: at least a first connecting element (13) is located on the first short side of the tunnel lining segment (11), and at least a second connecting element (14) is located on the first short side of the tunnel lining segment (11); the connecting elements (13, 14) of two tunnel lining segments (11) form a connection (15) in a connecting region (12); the connecting elements (13, 14) each have at least one main body (30, 40); at least one flange portion (33, 43) is provided on each main body (30, 40); and a frictional connection (15) between the connecting elements (13, 14) is provided via the at least one flange portion (33) of the first connecting element (13) via the at least one flange portion (43) of the second connecting element (13).
