A clamp binder for clamping about a material portion such as a constricted and portion of bags or of sausage casings, comprising a U-member (6) for insertion over the material portion from one side thereof, an apertured cross member (8) mountable against the opposite side of the material portion for receiving through its aperture the free leg ends of the U-member (6) as the material portion is clamped between the cross member and the base portion of the U-member, and a wedge member (20) adapted to be forced into the space between the free leg ends for bending these outwardly into a locked position in which the U-member is prevented from retraction from the cross member, the wedge member being formed of two half-pieces (20) integrally associated with the respective free leg ends of the U-member (6) by a breakable connection (18), such that the half-pieces will be jointed into a combined wedge member when they are caused to be displaced towards the locking position, whereby the wedge will automatically assume its correct position prior to its being forced into the locking position. |
