The invention pertains to a hose fitting particularly suitable with hose having a helical convoluted inner tube, and wherein the hose is formed of a synthetic plastic material. The fitting includes a tubular nipple having a helical projection upon which the hose inner tube is threaded, and a socket crimped upon the hose supported upon the nipple includes serrations for compressing the hose at predetermined locations. The nipple configuration aids in maintaining the hose upon the nipple in a fluid tight manner, and a socket tang receiving groove defined in the nipple axially maintains the socket in predetermined relationship to the nipple.
