Abstract: A coupling device for connection and disconnection of bottomhole equipment includes a male part having a stinger with locking grooves and a female part includes a receptacle and a housing. The female part further includes a hold open sleeve below the receptacle, locking dogs arrange between the housing and the hold open sleeve, a locking sleeve arranged below the locking dogs, and a verifying bolt. By joining the male and female parts, the coupling device will lock automatically, as the hold open sleeve is pushed into the locking sleeve by the stinger, after which the locking dogs are pushed into the grooves of the stinger, after which the locking sleeve is pushed up over the locking dogs locking the locking dogs, after which the verifying bolt once the locking sleeve is in locking position will be pushed into an adapted opening in the locking sleeve, thereby verifying correct locking.

Abstract: Coupling device (1) for connection and disconnection of bottomhole equipment, comprising; a male part (2) having a conically shaped stinger (3) with locking grooves (4), which male part is arranged at the end of a coiled tubing; and a female part (5) comprising a receptacle (7) in an upper end (6) and a house (8) that constitutes the outer part of the female part from the receptacle to a lower end (9), which receptacle has conical shape adapted to receive the stinger of the male part, distinguished in that the female part further comprises: a hold open sleeve (10) within the house towards the upper end, adjacent and below the receptacle, which hold open sleeve is axially displaceable in the house in direction towards the lower end and has an internal diameter smaller than the receptacle; locking dogs (11) with a biasing device (12) pushing the locking dogs radially inwards, which locking dogs are arranged between the house and the hold open sleeve; a locking sleeve (13) with a biasing device (14) pushing the
