The device has two coupling elements (10, 12) i.e. circular disks, which are divided into two semicircular segments (16, 18) at a dividing surface (14). The dividing surface runs right-angled to sliding surfaces (24) of the coupling elements. The coupling elements have circular undercut grooves (26, 28, 30, 32) in the sliding surface. The grooves run through the segments and flush with each other. The grooves receive semicircular latch plates (34, 36) whose cross section is complementary to the combined cross sections of the two grooves, where the plates are movable into the grooves. |
