Abstract

A coupler assembly for supplying different fluids has a base member adapted to supply one fluid through a first socket member and a second different fluid through a second spaced socket member. A hose terminal fitting has a pair of spaced tubular plugs of different diameters for entry into said socket members. One of the socket members has a hook which is engaged by a latch on the hose terminal fitting for locking the tubular plugs against withdrawal from the sockets. Advantageously the latch is spring biased into the latching position and has a cam surface to provide for the camming of the latch over the hook as the tubular plugs are moved into the sockets. Preferably the hook lies in a plane substantially perpendicular to the axes of the plugs and the latch is mounted for sliding movement transversely of the hose terminal fitting.
