Abstract
A clasp is configured to engage an end of a tube. The clasp has a shaft that is insertable into a tube. The clasp includes a housing with clamping blocks that are spaced circumferentially around the shaft. The clamping blocks are moveable between a disengaged position in which the clamping blocks are spaced radially outwardly from the shaft at a distance sufficient such that a tube is insertable between the shaft and the clamping blocks, and an engaged position in which the clamping blocks are positioned radially inward of the disengaged position toward the shaft and are configured to press a tube disposed between the blocks and the shaft against the shaft. The clasp has at least one actuator engageable with at least one clamping block of the plurality of clamping blocks to move the at least one clamping block between the disengaged position and the engaged position.
