A connector for connecting a first wellbore tubular to a second wellbore tubular, the connector comprising: a tubular housing having an internal bore which receives the first wellbore tubular, the tubular housing being connectable to the second wellbore tubular and comprising an internal surface which faces the internal bore and a ramp assembly arranged around the internal surface, the ramp assembly comprising: a plurality of elongate ramp arrays, each ramp array comprising a plurality of ramps which are inclined towards the internal bore; and a plurality of elongate channels which are arranged relative to the ramp arrays so that arrays which are adjacent are separated by an elongate channel; a slip body which is insertable into the internal bore of the tubular housing, the slip body comprising an internal passage which receives the first wellbore tubular, an internal surface which faces the internal passage and which comprises at least one slip tooth for engaging the tubular, an external surface and a ramp assembly arranged around the external surface, the ramp assembly comprising: a plurality of elongate ramp arrays, each ramp array comprising a plurality of ramps which are inclined away from the slip body, the ramp arrays of the slip body adapted to cooperate with the ramp arrays of the tubular housing to cause said slip tooth to grip the first wellbore tubular; and a plurality of elongate channels which are arranged relative to the ramp arrays so that arrays which are adjacent are separated by an elongate channel; in which the elongate ramp arrays of the slip body are each alignable with a respective elongate channel of the tubular housing, so that the slip body can be inserted into the tubular housing; and in which the slip body is rotatable within the tubular housing, so that the ramp arrays of the slip body can each be brought into alignment with a respective ramp array of the tubular housing. a tubular housing having an internal bore which receives the first wellbore tubular, the tubular housing being connectable to the second wellbore tubular and comprising an internal surface which faces the internal bore and a ramp assembly arranged around the internal surface, the ramp assembly comprising: a plurality of elongate ramp arrays, each ramp array comprising a plurality of ramps which are inclined towards the internal bore; and a plurality of elongate channels which are arranged relative to the ramp arrays so that arrays which are adjacent are separated by an elongate channel; a plurality of elongate ramp arrays, each ramp array comprising a plurality of ramps which are inclined towards the internal bore; and a plurality of elongate channels which are arranged relative to the ramp arrays so that arrays which are adjacent are separated by an elongate channel; a slip body which is insertable into the internal bore of the tubular housing, the slip body comprising an internal passage which receives the first wellbore tubular, an internal surface which faces the internal passage and which comprises at least one slip tooth for engaging the tubular, an external surface and a ramp assembly arranged around the external surface, the ramp assembly comprising: a plurality of elongate ramp arrays, each ramp array comprising a plurality of ramps which are inclined away from the slip body, the ramp arrays of the slip body adapted to cooperate with the ramp arrays of the tubular housing to cause said slip tooth to grip the first wellbore tubular; and a plurality of elongate channels which are arranged relative to the ramp arrays so that arrays which are adjacent are separated by an elongate channel; a plurality of elongate ramp arrays, each ramp array comprising a plurality of ramps which are inclined away from the slip body, the ramp arrays of the slip body adapted to cooperate with the ramp arrays of the tubular housing to cause said slip tooth to grip the first wellbore tubular; and a plurality of elongate channels which are arranged relative to the ramp arrays so that arrays which are adjacent are separated by an elongate channel; in which the elongate ramp arrays of the slip body are each alignable with a respective elongate channel of the tubular housing, so that the slip body can be inserted into the tubular housing; and in which the slip body is rotatable within the tubular housing, so that the ramp arrays of the slip body can each be brought into alignment with a respective ramp array of the tubular housing.
