Abstract
A surgical safety device to be fixed externally to the body of a patient fitted with a body tube for securing the body tube against unintentional displacement into or out of the patient, comprises two relatively rotatable tubular members telescoped together and defining a bore for receiving the body tube, and an elongate flexible element located in the bore and having its opposite ends fixed to the respective members. When the tubular members are rotated the flexible element wraps itself around the tube and grips it to prevent longitudinal displacement through the safety device.
