A device for connecting and disconnecting a first tubular conduit mobile in longitudinal translation inside a second fixed tubular conduit of the type comprising a longitudinally sliding mobile piece and which, for locking, bearing by an inclined bearing surface on a bearing surface of a mobile detent, causes said detent to swing through an opening formed in the wall of the fixed conduit into a groove formed in said mobile conduit. The means for driving the sleeve comprise a finger projecting through an aperture formed in the wall of said fixed conduit and sliding in a housing formed in the thickness of this conduit, for locking, under the effect of the thrust exerted by the downward movement of said mobile conduit onto said finger by means of a shoulder with which said mobile conduit is provided and, for unlocking, by sliding in the reverse direction under the effect of hydraulic or mechanical means such as a rod. Mechanical anchorage, separate from the hydraulic connection, is effected by simply driving in said mobile conduit.

A device for connecting and disconnecting a first tubular conduit movable in longitudinal translation inside a second fixed tubular conduit of the type comprising a mobile piece in the form of a longitudinally sliding sleeve and which, for locking, by bearing with an inclined bearing surface of at least one mobile detent, causes said detent to swing through an opening formed in a wall of this second tubular conduit into a groove formed in said mobile tubular conduit, wherein the drive means for causing longitudinal sliding of said sleeve comprise at least one radial finger projecting through an aperture formed in said wall of said fixed tubular conduit and sliding in a housing formed in the thickness of said wall of the fixed conduit, during locking, under the effect of the thrust exerted by the downward movement of said first mobile tubular conduit onto said finger by means of a shoulder due to the change of diameter and with which said mobile conduit is provided and, during unlocking, by sliding in the opposite direction under the effect of hydraulic or mechanical means.
