Abstract
A stopcock for controlling ducts in a medical endoscopes passing flux media, including a housing made of a hard material and rotatably receiving a conical plug in a conical seat crossed by a duct. The housing subtends, in the direction of the axis of rotation and beyond the larger opening of the conical seat, a bearing collar which supports a rotary body that is rotatable about the axis of rotation. The rotary body is fitted outside said housing with a handle and is rotationally coupled with the plug. The rotary body is axially displaceable and biased by a spring relative to the plug and is further fitted with a radially elastic detent device, which in the assembled state of the stopcock is configured inside the housing. The rotary body, by operation of the detent device, acts in a locking manner against the spring action on the bearing collar. The rotary body includes a prefabricated rupture site that, following deliberate rupture, exposes the snap-in device.
