A combination valve device 28 for an endoscope comprises at least two valves 30,30', each comprising a valve body 32 and a movable shaft 34. A common mounting 38 comprising a body provided with at least one aperture 42,44 for receiving the valves 30,30', and attachment means 40 for releasably attaching the device 28 to an endoscope control body 22 is also taught. In a preferable arrangement the common mounting 38 comprises two valve receiving apertures 42,44, each provided in enlarged end portions 43,45 of the mounting 38. An extendible and compressible connecting portion 46 may further be provided between the end portions 43,45 such that the distance between them may be varied. This facilitates insertion of the combination valve device 28 into the endoscope control body and accommodates any variation in the distance between the sockets on the control body which receive the valves 30,30'.
