The present invention relates to a housing (35) for an implant (25), a holding piece (1) to connect the implant (25) to the housing (35), and to an insertion tool (20) for inserting the implant (25) into an implant site. The holding piece (1) comprises at least one resilient element (45) for detachably connecting to the implant (25) with a first retentive force and a tool retention means to connect to the insertion tool (20) with a second retentive force which is greater than the first retentive force. In between the two ends the holding piece (1) features a housing connection segment (30) for connecting the holding piece (1) to the housing (35). On a distal end the insertion tool (20) comprises torgue transmission means, which transmit torgue directly to the holding piece (1) and/or to the implant (25).
