1 Claim. (Cl. 285-—169)
My present invention relates to a coupler par
ticularly adapted for coaction with a jaw coupler
of the kind that becomes disconnected from a
lubricant reception ?tting when swung to an an
tube I4 for coaction of the jaws I3b of the coupler

to readily slide over the coupler I2 as shown in
Fig. 1.

One object of the invention is to provide such
The tube I4 has a ring-like stop ?ange I8 for
coaction with a stop ?ange I9 of the sleeve I5.
Another ring-like ?ange 25 is provided on the
