Abstract
Abstract Disclosed herein is a retaining clip for the sheath used to protect a catheter tube from contamination during insertion of the guiding needle. The clip is designed to snap over the hub of the needle and at the same time clasp the mouth of the sheath about the hub. The clip includes a curved body portion and a pair of curved depending legs. An upturned neck extends from the body portion to facilitate removal of the clip after the needle has been inserted.
