A securement device for securing a rectal tube is disclosed. The securement device has a hollow cylindrical tube sized to accommodate a rectal tube, the hollow cylindrical tube having an opening at a first end and at a second end and a split running in an axial direction from the first end to the second end that allows a rectal tube to be snapped into the hollow cylindrical tube. The securement device also has one or more flat supports connected to the second end of the hollow cylindrical tube, each coated with an adhesive that can secure the device to the skin of a patient. Each flat support has a limited length connection with the hollow cylindrical tube, such that at least a portion of the circumference of the second end of the hollow cylindrical tube is not connected to the flat support.
