Abstract
An apparatus (23) is constructed having a pair of side gripping members (32, 34) which are pivotally coupled by hinges to an intermediate gripping member (36). These gripping members (32, 34, 36) have a l/d (length-to-diameter) ratio of approximately 5:1 to distribute compressive forces over a relatively large area. Inner gripping regions (46, 48, 50) of the members (32, 34, 36) are configured having frictional surfaces (46, 48, 50) which frictionally grip a tubular structure, such as a bi-stem (12). A latch (51) having catches (56) is positioned on one of side gripping members (34), and a catch (62) is positioned on the opposite side member (32) for engaging the catches (56), latching the apparatus (23) closed around the bi-stem (12). Handles (68, 70) are centrally affixed to an exterior region of side members (32, 34) and allow the apparatus (23) to be readily closed around the bi-stem (12) and also allow manipulation of the bi-stem (12). These handles may be removed when the apparatus (23) is used as a repair device.
