A forceplike instrument having rollers for clearing the contents of flexible tubing. The forcep comprises a pair of elongated arms pivotally joined at one set of ends and having handle loops on the other set of ends to receive the fingers of an operator's hand. Slight matching bends are formed in the arms midway of their length, and each arm is provided with a roller journaled normal to the arm length whereby a flexible tube may be gripped between the rollers when the forcep is closed. A tube restraining link extends between the outer end of one of the rollers and its arm.
