摘要:
A carrier easily securable within, and quickly releasable from, a standard pirn or like tubular article having an internal annular flange member within an otherwise hollow tubular body. The carrier is secured by means of a flexible washer which once positioned inside of the annular flange is held in locking engagement with the assistance of an intermediate member abutting the washer to prevent it from flexing. A stabilizing collar secures the flange from the other side thus clamping the flange between washer and collar. The pirn or other article may be released by shifting the washer away from the intermediate supporting member to allow the washer to flex thus permitting the withdrawal of the carrier. In another embodiment, the carrier is designed to be placed over a carried member having an external flange. The washer flexes during engagement to pass over the flange to the carrying position and is prevented from flexing in the opposite direction by an abutting member until the carrier is released.
