ABSTRACT:
It allows quick and effective coupling of a first duct end (female member) and a second duct end (male member). The male member includes an outer circumferential groove and the female member has two outer protrusions defining respective inner recesses adapted for receiving sealing and locking gaskets. When assembled, the female member extends to the male member without covering the circumferential groove thereof. A fastening clip is provided fitted into the groove of the male member and also into the groove defined between the protrusions of the female member, holding them axially in place.
