To complete a transfer of solid material such as mulch, multiple hoses may have to be connected together, therefore, such hoses have hose connection fittings attached at their ends. A hose connector has a male fitting connected to a first hose and a female fitting connected to the second hose. The male fitting may be inserted into the female fitting and the two fittings are secured together thereby connecting a first hose to a second hose. The hose connector has a locking assembly consisting of set screw, a radial hole defined in the female fitting, and a recess for receiving the set screw in the male fitting.

Pipe coupling: a male portion (13) provided with a series of spaced keys (15); a female portion (14) provided with a series of spaced keyways (16) so the keys are a sliding fit; a fastener including a male portion fitting (17) secured to or formed in the male portion (13) and providing at least one internally screw-threaded bore (17b); a female portion socket attached to or formed in the female portion, said female portion socket (18a) including a central aperture (23) shaped to receive a plug (24), both the female portion socket and the plug being radiused to match the radius of the female portion; a securing bolt (27) dimensioned to fit in a corresponding fixing aperture (26) formed in said plug and engage with said bore (17b); wherein when the at least one fastener is assembled the plug is a circumferential clearance fit in the female portion socket.
