Abstract: A clamping ring, for clamping an end collar of a protective bellows to one end of a universal joint in a vehicle transmission, is made of resilient material having two overlapping end portions. One end portion has a tongue extending through a slot defined in the other end portion. In its relaxed state, the material of the ring holds the tongue in an initial position in the slot. When the ring is placed over the end collar of the bellows, the ring expands slightly to permit this, the tongue moving towards a "high" stop at one end of the slot. The ring then resiles slightly so as to hold itself on the bellows. When the bellows, with the ring in position, is placed over the end of the universal joint, the ring once more expands slightly to permit this. The ring is then tightened by moving the end portion until a hook engages a shoulder on the other end portion, the tongue moving towards a "low" stop at the other end of the slot.

Abstract: For tying a compressed bale tending to expand primarily along a major axis, a bale tie made preferably from steel wire or alternatively from steel strap is bent to form two marcelled portions, which are characterized by sinusoidal undulations, which are oriented so as to be generally parallel to the major axis, and along which the tie can straighten to absorb tensile forces. A joint is formed at the opposite ends of the tie. Where bent to form the marcelled portions, the tie has an ultimate strength less than the ultimate strength of an undeformed portion of the tie but more than the ultimate strength of the joint. An apparatus for forming a wire with a marcelled portion comprises upper rolls and lower rolls, which are rotatably mounted and respectively on an upper block and a lower block. The upper block is pivotably mounted upon to the lower block.
