In the open position, spacing is provided between the clip and the holster so as to receive an article. In the gripping position, the clip is disposed such that, when an article is disposed between the clip and the holster, the article is gripped by the clip against at least one gripping surface portion of the holster under the force effecting biasing of the clip towards the gripping position. When the clip is disposed in the gripping position, and a handheld electronic device is received and supported by the pocket, coupling of the handheld electronic device to the article is thereby effected. When the coupling of the handheld electronic device to the article is effected, the minimum distance between the handheld electronic device each one of the at least one gripping portion of the holster is at least eighteen (18) millimetres. | 11-18-2010 |
