Adapter for male connector and male connector with adapter

An adapter that is attachable to and detachable from a male connector,

• the male connector comprising a rod-shaped male member that has a flow channel, a lock lever that is located opposite to the male member, a claw that protrudes from the lock lever toward the male member, and a cover that houses the male member,
• wherein the lock lever is elastically swingable so that the claw moves away from the male member,
• the cover includes an outer circumferential wall that is elastically and compressively deformable in a longitudinal direction of the male member, and a head portion that is provided at one end of the outer circumferential wall, and
• the cover is configured such that a leading end of the male member protrudes from the head portion when the outer circumferential wall is compressively deformed,
• the adapter comprising a first end portion and a second end portion,
• wherein the adapter has a through hole that penetrates the adapter and allows the first end portion to be in communication with the second end portion,
• the first end portion includes a hollow tubular portion in which the through hole is provided,
• a first projection and a second projection are provided on an outer circumferential surface of the tubular portion, and the second projection is located on a base end side of the tubular portion with respect to the first projection,
• the adapter can be connected to the male connector at a first position where the claw of the male connector is engaged with the first projection and at a second position where the claw of the male connector is engaged with the second projection,
• when the adapter is connected to the male connector at the first position, the flow channel of the male member is sealed with the cover, and
• when the adapter is connected to the male connector at the second position, the adapter compressively deforms the outer circumferential wall of the cover so that the flow channel of the male member is in communication with the through hole of the adapter.
