An arrangement by a piston-and-cylinder unit, comprising a cylinder member (1) and a piston member (2), movable therein, to which a piston rod (4) is connected. The cylinder member consists of a barrel pipe (7) and closure portions (6) at each end (5) of the cylinder member, the closure portion at one end exhibiting a bush (8). The bush is provided with a through bore (9) for the piston rod (4) and is enclosed by an end portion of the barrel pipe, said end portion being bent radially inwards, towards the piston rod and over a first circumferential surface (16) of the bush. The bush (8) is provided with a collar portion (14), exhibiting an external second circumferential surface of the bush, enclosing the circumference of the piston rod and extending axially beyond the inwardly bent portion. The inwardly bent portion (18) of the barrel pipe terminates in a circumferential edge (19), located adjacent to a positive corner (22) of the bush, formed between the first circumferential surface (16) and the second circumferential surface.
