1. A gastrostomy tubing system comprising:
a gastrostomy tube comprising a distal end and a proximal end, the distal end is configured to be positioned in a stomach of a subject and the proximal end is configured to extend outside the subject's body; a dismantlable retention structure connected to said distal end of said tube and configured to secure the tube to an inner wall of the stomach when the distal end is inside the stomach, and, when the tube is to be removed, to dismantle from said tube upon external manipulation and facilitate removal of the tube, while it is held inside the stomach; and a gripping member configured to associate with said tube and said dismantlable retention structure, said gripping member is operable to change from a first position in which it is associated with both dismantlable retention structure and tube, to a second position in which it grips the dismantlable retention structure while allowing release and replacement of the tube.
