1. A breast prosthesis having an adaptable volume, wherein the breast prosthesis has
a first shell body,
a second shell body peripherally connected thereto,
a fluid space arranged between said shell bodies, and
a valve tube composed of a flexible material, reaching into the fluid space from the outside in the connection region between the shell bodies, and projecting beyond the connection region into the fluid space,
the section of the valve tube projecting into the fluid space is at most not connected to only one of the shell bodies,
the valve tube comprising an internal step where an inner diameter reduces in size in a the radial direction toward the fluid space and having an inclined step surface obliquely extending to an axis of the tube,
said step positioned inwardly from a weld seam in the radial direction, and arranged as an abutment to prevent too deep penetration of a pump needle, and
the valve tube is welded between the shell bodies.
