Abstract

An improved coupling device (e.g., 134) has a first section (e.g., 135), a second section (e.g., 136), and a sleeve member (e.g., 138) mounted on one of the coupling sections and arranged to selectively engage the other coupling section. The sleeve member is provided with a weakened portion (e.g, 156). The weakened portion is formed of a suitable material and is so configured and arranged as to permit the two coupling sections to be physically separated from one another through thermally-induced flexural deformation of the weakened portion, without rotation of the sleeve member relative to either section, when the temperature of the weakened portion is greater than about 200 °F but less than about 300 °F, and preferably about 266 °F.
