Provided is a coupling for fluid wherein the operation of connecting a male coupler and female coupler to each other can be easily performed. A first coupler (4) is equipped with a tubular first main body (10); and an outer tube (38) which is positioned around the outer periphery of the first main body (10) and protrudes from the end of the first main body (10), and at the end of which a first engagement section (70) and a second engagement section (38a) are provided. A second coupler (5) is equipped with a second main body (50) which is to be inserted along the inner peripheral surface of the first main body (10). A third engagement section (52a) capable of being engaged with the first engagement section (70), and a fourth engagement section (51) capable of being engaged with the second engagement section (38a), are provided in the second main body (50). The second engagement section (38a) and the fourth engagement section (51) are engaged with each other by matching the phase of the first engagement section (70) and that of the third engagement section (52a) with each other in the process of engaging the first engagement section (70) with the third engagement section (52a). As a result, the outer tube (38) and the second main body (50) are connected to each other.
