Abstract
A coupling arrangement consists of two cylindrical parts, a shell having three radially extending projections and a track part having three helical tracks on its internal surface for the reception of the projections. Each track is provided with a locking member consisting of a rotatable pin having a recess. The projections enter the recesses on relative rotation of the two parts and are retained in this position by a compression spring which tends to urge the two parts apart and hold the projections in the recesses. The parts can be separated by compressing the spring and relatively rotating the parts in the opposite direction, or a sleeve surrounding the track part, which normally prevents rotation of the pins, can be moved axially on the track part to allow the pins to rotate and permit the shell and its projections to be withdrawn axially from the track part.
