The male connector (1) includes a connector body (10) and a lock nut (50). The connector body (10) includes a male luer (11), first female threading (41) that surrounds the male luer (11), a base end portion (20) that is inserted into a tube (8), a fixed protrusion (21) formed on the base end portion (20), and a spiral protrusion (32) between the male luer (11) and the base end portion (20). The lock nut (50) includes second female threading (52) that is screwed together with the spiral protrusion (32). When the spiral protrusion (32) and the second female threading (52) are screwed together, the base end portion (20) and the lock nut (50) clamp the tube (8). First rotation prevention mechanisms (14, 54) that engage with one another are provided on the connector body (10) and the lock nut (50) such that the lock nut (50) does not rotate relative to the connector body (10) when the tube (8) is clamped. |
