ABSTRACT:
A reusable heat-recoverable connecting device having an annular driver member and a circumferentially split annular spring biasing means inside and generally concentric with the driver member. The spring biasing means normally exerts an outward radial force against the inside surface of the driver member. The driver member is made from a heat-recoverable metal having a martensitic state and an austenitic state. The driver member is expanded radially outward by the spring biasing means when the driver member is in its martensitic state to facilitate insertion of a substrate. The driver member recovers to its non-expanded dimension when it returns to its austenitic state to cause engagement between the spring biasing means and an inserted substrate.
