A wireline connector device (10) for use in wireline intervention operations comprises a housing (18) connected to a first wireline conduit (L), a piston sleeve (46) located within the housing, and a collet device (60) configured to receive and retain a second wireline conduit, the collet device having a plurality of collet fingers (58) arranged within the piston sleeve, which is movable within the housing to open and close the collet fingers. Optionally a restrictor (57) can be configured to control the movement of the piston sleeve, and can be adjustable to lock the piston sleeve in the second position when the collet fingers are closed around the second wireline conduit. Typically at least one indicator rod (55) projects from the housing, and the piston sleeve engages indictor rod in the second position. |
