The invention is a device that improves safety and efficiency of colonoscopy by preventing loop formation. It is the plastic overtube with the longitudinal split. The split allows the placement over the shaft of the endoscope when colonoscopy is already in progress and a loop is formed that hinders the further endoscope insertion. The overtube is segmented by oval openings of the split to facilitate placement and to allow using optimal lengths of the overtube. The fastening mechanism is used to close and secure the overtube on the shaft of the endoscope and then it is pushed inside the colon by sliding over the endoscope. Once in place, the overtube is kept steady and provides the semi-rigid conduit for further endoscope insertion. This conduit permits the axial force exerted by the operator to be translated to forward movement of the endoscope tip and eliminates dangerous loop formation.
