Abrégé

The invention relates to a device for detachably fixing two parts (1, 8) of a device for generating compressed air, in particular of a bicycle pump, to each other, which parts can be moved in relation to each other, wherein a substantially cylindrical end region of the pump piston (8) facing a bicycle saddle is designed to have a diameter (7) that is enlarged in relation to the part of the pump piston which is guided in the sleeve (1) such that the region of the enlarged diameter (7) and a free end region of the sleeve (1) are surrounded by a union nut (4), which union nut has an internal thread (5) in an end region, and the internal thread (5) of the union nut (4) can be detachably connected to a thread (3) arranged on the sleeve (1) or on the region of enlarged diameter (7) of the pump piston (8), in order to design both the union nut (4) and one of the parts (1, 8) of the seat pillar that can be moved in relation to each other to have stops that interact with each other.

Abrégé

In a device for detachably fixing to each other two relatively
movable parts (1, 21) of a device for generating compressed
air, in particular a bicycle pump, a substantially cylindrical
end region of the pump piston (21) facing a bicycle saddle is
designed to have a diameter (7) enlarged relative to the part
of the pump piston guided in the sleeve (1), the region of
enlarged diameter (7) and a free end region of the sleeve (1)
are surrounded by a union nut (4) provided with an internal
thread (5) in an end region and the internal thread (5) of the
union nut (4) is detachably connectable to a thread (3)
arranged on the sleeve (1) or on the region of enlarged
diameter (7) of the pump piston (21), in order to design both
the union nut (4) and one of the two relatively movable parts
(1, 21) of the seatpost with interacting stops. (Fig. 1)
