A gripper having a pair of straps for safely opening a narrow cylindrical article, by wrapping a closure on a narrow cylindrical article with a first strap and wrapping the narrow cylindrical article with a second strap, grasping each and rotating each in opposing directions, releasing the friction holding the closure on the article. The gripper is made from a sterilizable elastomeric material for use in a medical setting such as a hospital or a laboratory. The pair of identical straps are connected by a band attached to a middle portion on each strap. The gripper opens a connector on a central venous catheter (CVC) lumen, a pair of clasps on CVC stabilization device, a connector on a urine collection bag to a Foley catheter, and a cap on a laboratory sample vial as non-limiting examples.
