An inexpensive, disposable rectal catheter which safely, gently and securely anchors the neck of a plastic bag within the patient's rectum. The device is of such simple construction that it may be both inserted and removed by the patient with one hand. The device features a stool-collecting bag having a narrow neck opening which is folded about a retaining member in the form of a cannula having a plurality of flexible, outwardly biased flanges which act to securely hold the neck of the bag against the inner wall of the rectum. To insert the retainer, an obturator is coupled to the tips of the flanges to hold same inwardly during insertion into the patient's rectum. The obturator is then removed, leaving the bag and retainer in place, which may be easily withdrawn after completion of a bowel movement by the patient.
