ABSTRACT:
A jointing device, which permits quick connection and disconnection of a corrugated flexible conduit, comprises a joint body having a cylindrical connector section for receiving the conduit, the connector section being formed with receive holes arranged circumferentially thereof, and a clasp axially slidably mounted on the joint body. The clasp has an outer cylinder axially slidably fitted on the connector section and covering the receive holes formed in the connector section, an inner cylinder slidably fitted into the connector section for receiving the conduit, and locking members connected at their respective fixed ends with the inner cylinder. The outer and inner cylinders are connected with each other. The locking members each have a free end portion thereof formed with a claw engageable with and disengageable from the conduit. The free end portion of each locking member is received in a corresponding receive hole when the free end portion is pushed radially outward by the corrugated flexible conduit. Each locking member is engaged at its claw with a groove or depression of the corrugated flexible conduit when the free end portion thereof is pushed radially inward by a corresponding receive hole-defining face of the connector section.
