A valve body (20) for an endoscope is moulded from polypropylene and has a straight through bore (27) to aid cleaning of the valve body. The valve body (20) has spaced external ribs (48, 50) which locate the valve body (20) with respect to the casing of a handle (10) of the endoscope. At one end the valve body (20) receives a threaded sleeve (30) which retains a slidable valve member (34) in position, a cap (42) being manually depressed against spring loading to open the valve and place a source of suction in communication with a side stem (38) which is intended to be connected to a passageway leading to the distal end of the endoscope shaft.
