A double-leg plug has its shanks connected together at one end by an arcuate hinge ligature which is of circular configuration when the shanks of the plug are brought together and inserted in a hole in a wall. The circular portion forms an eye in which a cable, tube, pipe or other elongated body can be received and clamped. The confronting faces of the legs, which can be externally toothed, are formed with a groove and a projection, respectively, limiting relative longitudinal displacement of the shanks when the legs are brought together. The depth of penetration of the shanks into the bore in the wall can be limited by an abutment. |
