  • Device retaining mechanism
    Patent number: 10357100

The clip (a) comprises at least one clip engagement structure and (b) is moveable between a released position and a locked position when the latch is in the second position. When the latch is in the first position and the clip is in the locked position, the latch engagement structure engages the clip engagement structure, such that the locked position is configured to cause the retaining pin to engage the device. When clip is in the released position, the latch engagement structure does not engage the clip engagement structure and the retaining pin does not engage the device.
