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.
