Abstract: A system for securely attaching a portable device to the clothing of a user is provided. The system utilizes an adjustable separator located between the first end of a portable device mounting clip and the device housing. By controlling the amount that the first end of the clip can be depressed, the separator also controls the size of the gap between the second end of the clip and the device housing. If the user wants to lock the clip in place, the separator is adjusted to prevent any movement in the first end of the clip.

Abstract: A system is provided for securely attaching a portable device to the clothing or other personal item of a user. The system utilizes a modified retaining clip, the retaining clip being pivotably mounted to the device housing. As modified, the retaining clip may be locked in a closed position, thus preventing the portable device from being easily dislodged from the selected personal article. In one embodiment, an adjustable separator is interposed between one end of the mounting clip and the device housing. By controlling the amount that the first end of the clip can be depressed, the separator also controls the size of the gap between the second end of the clip and the device housing. In a second embodiment, the modified retaining clip includes a pair of flexible projections proximate one end of the clip as well as a compression mechanism. The compression mechanism controls the gap between the two flexible projections, thus controlling the relative flexibility of the projections.
