ABSTRACT Male and female parts are included in a coupling device which is provided with locking members for said parts. The locking members comprise a lock nut which is adapted to be fitted on the female part and a locking ring which can be inserted between two opposite locking surfaces on the male part and the locking unit to prevent mutual pulling-apart movements between the male and female parts. An opposing member is adapted to impart to the locking unit a first distinct longitudinal displacement position in relation to the female part. In this longitudinal displa- cement position, at least one sealing ring is inserted between the male and female parts and the male park is comparatively loosely suspended in and sealed with respect to the female part by said sealing ring. The opposing member is also adapted to yield to the locking unit when a certain longitudinal displacement force or moment is imparted to this by the opposing member, for which the locking unit assumes a second longitudinal displacement position. In the latter position, a front sealing surface on the male part cooperates with a seat provided in the female part to achieve a rigid connection between the parts and a reliable sealing between said parts which may be additionally sealed by one or more sealing rings.
