1. A tool for inserting an ear-tip of a hearing aid into an auditory canal of an end user, comprising
a first part and a second part,
wherein an end of the first part and an end of the second part form a cavity for receiving a holding portion of the ear-tip,
the first part and the second part being arranged next to each other and being connected by means of at least one pivot joint,
the at least one pivot joint defining a first portion and a second portion of both the first part and the second part, in that the first portions of the first part and the second part, respectively, extend from first ends comprising the cavity to the at least one pivot joint, and the second portions of the first part and the second part, respectively, extend from the at least one pivot joint to second ends opposite of the cavity along a longitudinal extension of the first part and the second part;
whereby the second portions of the first part and the second part are movable in relation to each other, and the first portions of the first part and the second part are movable in relation to each other, upon pressing the two second portions together in a direction perpendicular to the longitudinal extension of the first part and the second part, resulting in a pivotal movement via the at least one pivot joint, whereby the first portions of the first part and the second part forming the cavity are moved apart, thereby enlarging a cross-sectional area of the cavity to release the holding portion of the ear-tip from the cavity; and
wherein at least the second portion of the second part is elastically deformable relative to the second portion of the first part so that, upon pressing the two second portions together in a direction perpendicular to the longitudinal extension of the first part and the second part, the second portion of the second part elastically deflects about the at least one pivot joint, thereby moving the first portion of the second part away from the first portion of the first part, while the second portion of the first part does not deflect.
