ABSTRACT:
A pipe-end protector depending on its being used as a cap or plug comprises a metal housing with a sleeve-like, elastomer inset or a metal plug with a sleeve-like, elastomer cover. To increase the strength of the protector, the metal housing or the metal plug--which always are tubular--are provided at their outer end with a flanged or folded, preferably rolled edge. To facilitate manufacture of the protector, the inset or the cover may consist of at least two part-cylindrical mating case-components.
