Abstract

A novel duct for inclusion in ductwork of the kind in which adjacent duct ends carry annular grooves (1', 2') which in use locate terminal radially inwardly directed flanges (3') of a split clamp ring (3) which in turn retains a flexible annular seal (5) whose radially inwardly directed terminal lips (5') make sealing engagement against the ducts. The duct is formed at its ends with annular clamp-locating grooves (1') and intermediate its ends with a flexible portion (1b), thus providing flexibility in ductwork of the type outlined without the need for extraneous coupling means.
