A drainable ostomy pouch has an outlet. Reinforcing members at the outlet
are deformable by application of manual pressure at their ends to distend
the outlet. The lateral edges of the reinforcing members may be offset,
which encourages the reinforcing members to consistently bend away from
each other. A peelable distributed mechanical engagement fastener secures
the outlet in a folded condition. The fastener parts are hook-hook type
plastic extrusions, and provide a snap-engagement. A security flap is
foldable under the outlet when in its folded condition. The outlet is
released in two stages.
