Claim 0:
1. A liquid spraying apparatus comprising a spray gun and a reservoir for a liquid to be sprayed, the reservoir having an outlet connectable to the spray gun to permit the liquid to be withdrawn from the reservoir in use, and the spray gun having an integral socket arranged for non-threaded engagement with co-operating connector means by means of which the reservoir is releasably secured to the spray gun, wherein the co-operating connector means on the reservoir comprises a tubular coupling member that is a push-fit in the socket, the tubular coupling member having a first portion that provides a fluid-tight connection between the tubular coupling member and the socket, and a second portion that is co-operable with the spray gun externally of the socket to inhibit rotation of the tubular coupling member in the socket without restricting relative axial movement between the tubular coupling member and the socket to engage/disengage the tubular coupling member, wherein a radial lug integral with the spray gun is spaced above the integral socket forming a recess that interacts with the second portion.
