A holding device for elongated instruments can include a channel for receiving therein an intermediate portion of an elongated instrument. The holding device can include a lock that includes a seat against which the elongated instrument can rest and a resiliently deformable retention arm that is movable relative to the seat. The lock, when in the securing state, can retain within the channel the intermediate portion of the elongated instrument to prevent the intermediate portion from one or more of translating or rotating relative to the device.
