An improved external catheter for incontinent males. The external catheter consists of three interrelated components. A generally tubular sheath having a fluid drainage tube connection at one end and a reinforcing ring at the other is adapted to fit loosely over the penis with the ring at the base of the penis. A frusto-conical seal of elastic material having a reinforcing ring at the base end is adapted to fit within the sheath with the ring at the base of the penis adjacent to the sheath ring. The wall of the frustom extends along the penis in snug engagement therewith. A nether garment to be worn by the patient has a penis-receiving hole surrounded by a collar. The collar has a circular channel means with the channel opening extending outwardly away from the penis. With all three components in place, the two rings are extended slightly and snapped into the collar channel, sealing the ring and sheath together and using the nether garment to resist forces tending to remove the sheath. This external catheter assembly is extremely resistant to seepage of urine or to being forced off of the penis by a sudden large flow of urine.
