ABSTRACT:
An apparatus is disclosed for coupling of tubular members using a strip of metal which is preformed with an arcuate bend portion having a limited length in relation to the overall length of the strip and including two bend portions having radii so related to the radii of the tubular members as to obtain enhanced gripping and enhanced ease of installation. The strip receives a gland ring and also a helical wire for seating in grooves of a flexible conduit and is otherwise constructed to obtain an enhanced seal.
