Abstract: An assembly of a male coupling part 200 and a stiff tube 100 is disclosed, the stiff tube 100 having an attachment means 110; and the male coupling part 200 requiring a relative axial displacement between the male coupling part 200 and the stiff tube 100 for connecting to a female coupling part 500, the male coupling part 200 comprising an axial through opening 210. The Assembly further comprises an element 300 detachably connected to the male coupling part 200 and slidably attached to the stiff tube 100, the element 300 having an opening 310 allowing relative axial displacement 340 between the male coupling part 200 and the stiff tube 100, and the attachment means 110 being movable within the opening 310. A method for coupling and un-coupling the assembly to a female coupling part is also disclosed.

Abstract: A multicoupling comprising a first and second part comprising a first and second set of connectors; and rotational means for connecting the first part and second part. The first set of connectors comprise a plurality of couplings, or a plurality of nipples, or at least one coupling and at least one nipple, or at least one electric contact and at least one of a coupling or a nipple. The second set of connectors comprise, correspondingly, a plurality of couplings, or a plurality of nipples, or at least one coupling and at least one nipple, or at least one electric contact and at least one of a coupling or a nipple. The rotational means actuates, by rotation, control means for at least one connector of the first and/or second set of connectors, and the rotational means and the control means are in one and the same first part or second part.
