A releasable coupling device having a cam-type interengagement between the inner surface of a cap member and the outer surface of a gripping member. The coupling device including a primary arrangement of cams and guide surfaces engageable therewith, upon rotation of the cap member to the clamping position, so as to deform the gripping member radially inwardly to gripping engagement with the outer periphery of the second tubular component. A secondary arrangement of cams and guide surfaces is engageable therewith, upon rotation of the cap member to the clamping position, so as to take up any radial clearance which may develop between the inner surface of the cap member and the outer surface of the gripping member as a result of radial inward deformation of the gripping member by the primary arrangement of cams and guide surfaces.
