The invention relates to a device for fixing a piston (1), or a piston rod attachment, to a piston rod (5), one of the piston (1) and the piston rod (5) having a hole (2) running in its axial direction, and the other of these having a portion designed for being received by the hole (2) for connection of the piston (1) and the piston rod (5). The device comprises an elongate locking means (10), at least one first opening (8a, 8b) in the piston and at least one second opening (9) in the piston rod (5), which openings (8a, 8b, 9) in the piston rod (5), which openings (8a, 8b, 9) extend in a different direction from said axial direction and are designed for receiving the locking means (10) for the purpose of bringing about said fixing. The elongate locking means (10) has a greater extent in its transverse direction, along at least a part of said means, than the extent of at least one of said openings (8a, 8b, 9) in its transverse direction, along at least a part thereof, for form locking between the locking means (10) and the opening. The invention also relates to a method for said fixing.
