A gastrostomy tube set includes a delivery tube assembly (12) and a supply tube assembly (14). The delivery tube assembly (12) includes a first tube (1 6) for placement in the stomach and a termination (20). A valve assembly (24) i s disposed in the fluid passage of the termination (20) and includes a housing and a valve body (34). The housing includes at least one flange (44) that protrudes radially outward. The supply tube assembly includes a connector (6 2) having a tubular male element (68) and a side wall (70) extending coaxially with the male element (68). The side wall (70) presents a lug (74) that protrudes radially inward toward the male element (68). The connector (62) i s coupled to the valve assembly by inserting the male element (68) into the infusion port, shifting the valve body (34) to an open positio, and rotating the connector (62) so that the lug engages the flange (44) to prevent the connector (62) from being pulled axially from the termination (20). |
