There is but a single joint j 5o socket piece and thus lock the parts against to be made Water-tight and that between the roo t faces of the head 9 and Wall l0. In my construction the nut cannot be removed and the screw threads are always protected from damage by blows from being dropped on the paving or other hard objects, and when the coupling is effected, there is no friction resulting from sliding of one part upon another. In 1ny device there is no necessity for holding the parts accurately While coupling as they bring themselves to proper seating by turning.

Having thus described my invention, what I claim is- 1. In a hose-coupling, the combination of the socket-piece having a nipple to receive one hose section and a laterally opening socket; a head-piece provided with a head adapted to enterand turn in the socket to interlock therewith, an internal sleeve longitudinally movable Within the head-piece, and having front and rear llanges for retaining it therein and a nipple for receiving the other hose section; and the nut threaded over the rear end of the head piece and having the internal flange engaging behind the rear fiange on the sleeve and thereby adapted to project the head beyond the head-piece, all substantialy as and for the purposes set forth.

2. In a hose coupling, the combination of the socket-piece having the nipple for the reception of one hose section, the sleeve having a bore corresponding to that ot' the socketpiece and terminating in a nipple for receiving the other hose-section and the means for forcing the sleeve against the socket-piece and making a water-tight connection which consists in the head surrounding the sleeve and adapted to enter the socket and the nut threaded to the end ot' the head-piece and having connection with the sleeve in rear of the head-piece, all substantially as and for the purpose set forth.

3. In a hose-coupling` the combination of the socket-piece connected with one hose-section and the co-operating part consisting of the sleeve for receiving the other hose-section and provided with the two flanges on its exterior surface, the head-piece conned between the two flanges and the nut screw threaded to the head-piece and engaging one of the flanges on the sleeve, all substantially as set forth.
