Abstract
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.

A connector element 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 one of a pine-cone and thorn profile having at least one ring, characterized in that an axially extending cylindrical area with an outer diameter corresponding to the inner diameter of the tubing or hose end is provided at a front end of the tubular part and in that a circumferential groove, rectangular in cross section, into which an annular seal of noncircular cross section is arranged, is formed in the cylindrical area, the seal having a rectangular cross section completly filling out the groove wherein the cross-section of the seal is rectangular only on the inside of the groove and is convex over the entire longitudinal extent on the outside of the groove, and the outside of the seal has a smaller radius in an area adjacent to the front end of the tubular part than in an opposite area.
