Abstract
A retention bolster for a flexible tube segment in a corporeal access tube assembly. The bolster includes a body molded in one piece of silicone rubber and cut into two legs along a portion of its length. One of the legs has a collar formed on its free end, with a lip under which the free end of the other leg nestles. To hold the legs together and grip a tube segment between them, an O-ring is rolled over the collar into a depression encircling both legs without contracting into the cut between the legs.
