A low profile gastrointestinal tube feeding system (10) having a securing device (12) for securing a feeding set (14) to a low profile gastrostomy tube (16) thereof disposed inside the viscera of a patients body so that inadvertent removal of the feeding set (14) from the gastrostomy tube (16) is prevented. The feeding set (14) includes hollow tubing (86) connected to a source of fluid at one end and a connection member (15) at the other end (103) for connection to the gastrostomy tube (16) and establishing fluid flow communication with the patient. The low profile gastrostomy tube (16) includes an external retention member (18) having legs (58) that seat and retain the external retention member (18) against the patients outer body and a tubular member (60) that is disposed inside the stomach or other viscera of a patient. The connection member (15) attaches to the external retention member (18) and is secured thereto using a securing device (12). The securing device (12) includes a top portion (26) and a bottom portion (30) which are adapted to simultaneously engage respective portions of the connection member (15).La présente invention concerne un système dalimentation (10) à tube gastro-intestinal court pourvu dun dispositif de fixation (12) pour fixer un ensemble dalimentation (14) à un tube de gastrotomie court (16) placé à lintérieur du viscère dun patient, de telle sorte quil est impossible de retirer par inadvertance lensemble dalimentation (14) du tube de gastrotomie (16). Lensemble dalimentation (14) comprend un tube creux (86) relié à une source de fluide à une extrémité et un élément de raccordement (15) à lautre extrémité (103) en vue de son raccordement au tube de gastrotomie (16) et assurant la communication par le fluide avec le patient. Ce tube de gastrotomie (16) comprend un élément de rétention externe (18) pourvu de pattes (58) qui fixent et maintiennent lélément de retenue externe (18) contre le corps externe du patient et un élément tubulaire (
