Connector element for tubing or hoses

摘要

A connector element is provided for tubing or hoses of elastically expandable material with a tubular part of inelastic material that can be inserted tightly sealed into a tubing or hose end and that features a so-called pine-cone or thorn profile. In order to simplify the handling and to improve the sealing effect, this connector element has an axially extending cylindrical area with an outer diameter matched to the inner diameter of the tubing or hose end at the front end of the tubular part. A circumferential groove, rectangular in cross section, into which an annular seal of noncircular cross section is arranged is formed in the cylindrical area.
