Handle comprises a locking structure formed by grooves in each part of the body, having a first locking position and a second locking position, in accordance with the slider first and second positions, respectively. Locking mechanism comprises an integrated with the slider spring, wherein at least part of the spring is wider than the channel, so that when the implant is held by the slider support member and the slider is in its first position, spring engages with the locking structure in the first locking position, and when the spring is compressed and the slider is moved into its second position, the spring engages with the locking structure in the second locking position.
