  • Publication number: 20190159858
    Abstract: A holding clip is designed to be fixed in a holding contour of a housing part of a sterile container and/or to be removed from the holding contour without tools. The holding clip has at least one at least partly spring-elastic clamping section designed to provide a clamping force to secure the identifying element and at least two holding sections that adjoin the clamping section on both sides and that are designed to engage into an undercut of the holding contour in a form-fitting and/or force-fitting manner. A sterile container can include such a holding clip.
