A sheet pile of concrete comprising a reinforcement (1) which is produced from composite material comprising fibres and a concrete casting (2) which extends between a first lateral end (3) thereof and an opposite second lateral end (4) thereof, the reinforcement (1) being embedded in the concrete casting (2). The sheet pile further comprises a terminal element (6) which is produced from a polymer material and which comprises a connection element (7) which is embedded in the concrete casting (2) and an engagement element (8) of the sheet pile (100) which is connected to the connection element (7). The connection element (7) and the engagement element (8) extend along a longitudinal axis (X) of the sheet pile, in which the engagement element (8) has a practically “C”-shaped cross-section and projects from the first lateral end (3) of the concrete casting (2). The second lateral end (4) of the concrete casting (2) comprises a concrete joint (9) which extends longitudinally along the longitudinal axis (X) and which is shaped so as to be connected in an interlocking manner to the engagement element (8) of a second sheet pile.
