Abstract
A coupling element system for an ostomy bag including a bag-side coupling element having a stomal orifice surrounded by a channel shaped member, a body-side coupling element having a stomal orifice surrounded by a rib-like member which can make snap-fit engagement with the channel shaped member, and a locking member. The latter member has radially inwardly deformable arms and is rotatable relative to the body-side coupling. The deformable arms are shaped and positioned so that upon rotation of the locking member in one rotary direction relative to the body-side coupling element they are deformed radially inwardly and over-lie a portion of the bag-side coupling element. The locking member may be generally annular with the arms arcuate in shape each with a blade portion and a leg portion which connects the blade portion to the remainder of the locking member.
