A hydraulic accumulator, particularly a piston-type accumulator, includes an accumulator housing (1) which defines a longitudinal axis (9), is provided with an opening that is concentric with the longitudinal axis (9) and is closed by means of a lid (11). The lid is secured in a form-fitting manner against axial forces by a wall portion (25) of the accumulator housing (1). The housing encompasses the lid and is radially deformed towards the inside. The hydraulic accumulator also includes at least one part (39) that is deformed perpendicular to the longitudinal axis (9) secure the lid (11) in a form-fitting manner against being twisted relative to the longitudinal axis (9).
