Claim 1
Independent Claim
141 words
Sealing means for a tubular casing having a plurality of cammed lugs equally spaced about the interior of a rim formed at the open end thereof, comprising, in combination: a circular cover adapted to be inserted in the rim of the casing for locking therewith, said cover having equally spaced about the periphery thereof a plurality of cammed lugs for rotatably engaging the lugs of the casing when said cover is rotated in one direction; and a U-shaped retaining clip having a pair of legs for compressively engaging the opposing surfaces of the casing rim between succeeding ones of the rim lugs and having a jutting portion on one leg for blocking the rotation of a selected one of said cover lugs in a direction opposite to said one direction thereby to retain said cover in locking engagement with the casing.
