1. Attachment system for detachably coupling a female tube end and a male tube end to each other in order to form foundation piles, the system comprising:
a cylindrical sleeve hole in a tube sleeve of the female tube end;
a corresponding cylindrical sleeve hole in a tube sleeve of the male tube end, the corresponding cylindrical sleeve hole being alignable with the cylindrical sleeve hole in the female tube end when the male tube end is being fitted in the female tube end;
a coupler comprising a cylindrical base body which is fittable in the cylindrical sleeve hole and the corresponding cylindrical sleeve hole when the cylindrical sleeve hole and the corresponding cylindrical sleeve hole have been aligned with respect to each other, in order to couple the female tube end and the male tube end to each other;
a blocking pin which is provided on, and extends radially with respect to, the base body, the cylindrical sleeve hole, or the corresponding cylindrical sleeve hole;
a blocking slot which is provided in the cylindrical sleeve hole or the corresponding cylindrical sleeve hole, or the base body, respectively, and in which the blocking pin is fittable; and
a blocker,
wherein the blocking pin and the blocking slot are arranged in such a way that the coupler is rotatable through an angle after the coupler has been fitted in the cylindrical sleeve hole and the corresponding cylindrical sleeve hole, wherein fitting of the coupler in the cylindrical sleeve hole and corresponding cylindrical sleeve hole fits the blocking pin in the blocking slot;
wherein at least one of the cylindrical sleeve hole and the corresponding cylindrical sleeve hole, and (ii) the base body are provided with corresponding sleeve slots which extend at least partly axially with respect to the respective sleeve hole or the base body,
wherein the sleeve slots together form a fitting hole after the coupler has been fitted in the cylindrical sleeve hole and the corresponding cylindrical sleeve hole and after the coupler has been rotated through the angle, and
wherein the blocker is fittable in the fitting hole in order to prevent the coupler from rotating in the cylindrical sleeve hole and the corresponding cylindrical sleeve hole.
