<p>The present invention provides an improved clamping ring for use in releasably holding a cover in assembled relationship with a drum and in assisting in retaining a strap in position on the drum when the drum is strapped to a pallet comprising a split ring having two ends positioned substantially adjacent to one another, a locking lever pivotedly connected adjacent one of its ends with one of the ends of the split ring, linkage means for pivotedly connecting the other end of the split ring with an intermediate portion of the locking lever, the pivotal connections being so constructed and arranged so that the locking lever is shiftable from an open position away from the split ring a-t which the split ring is in an expanded position to a locking position adjacent surfaces of the split ring at which the split ring is in a contracted position, a hinge strap bent back upon itself to form a pivot bearing connected to said one end of the split ring and the locking lever hingedly connected at the bearing, a latch pivotedly connected with the split ring and adapted to be shifted from the unlatched position away from the split ring to a latched position and into engagement with the lever when the lever is in its locked position, and confining means on the outer surface of the clamping ring adapted to receive and retain at least one strap from slipping when the strap is used to fasten the drum to the pallet.</p> |
