• said valve and connector assembly comprising a suction connector part, a valve housing main body, a plunger, and a valve housing lid,
• wherein said valve housing main body is accommodated in said valve accommodation passage so as to extend from the interior of the handle through said valve accommodation passage and beyond said external wall surface, and
• wherein the plunger is so accommodated in the valve housing main body that the plunger extends from the interior of the handle through said valve accommodation passage and beyond said external wall surface,
• wherein the endoscope further comprises a suction channel tube and a suction port at a distal end of the insertion cord,
• wherein the valve housing lid comprises an entry pipe connected to the suction channel tube,
• wherein the suction channel tube is in fluid communication with the suction port at the distal end of the insertion cord,
• wherein the valve housing main body comprises an exit pipe connected to said suction connector part,
• wherein the suction connector part is accommodated in said wall, and
• wherein said suction connector part comprises an oblong engagement flange in frictional engagement with said wall.

An endoscope comprising a handle and an insertion cord, said handle comprising a handle housing part, an interior, and a valve and suction connector assembly,
