Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 152 words
A clip for mounting a disc in an aperture in a panel, comprising a tubular body portion which can be inserted through the aperture in the panel, and external abutment on said tubular body portion adapted to limit insertion of said body portion of the clip through the aperture, resiliently, radially compressible external projections on said body portion spaced from said external abutment and adapted to engage the panel and retain the clip in position, an internal rib on said body portion, and a plurality of resilient tongues extending from the internal surface of the body portion, each tongue having a free end face spaced from and facing the rib, the disc being trapped, in use, between the rib and the end faces of the tongues, said rib being disposed in a plane lying between the plane of the end faces of the resilient tongues and the plane of the external abutment.
Claim 2
Dependent Claim 152 words
A clip for mounting a disc in an aperture in a panel, comprising a tubular body portion which can be inserted through the aperture in the panel, and external abutment on said tubular body portion adapted to limit insertion of said body portion of the clip through the aperture, resiliently, radially compressible external projections on said body portion spaced from said external abutment and adapted to engage the panel and retain the clip in position, an internal rib on said body portion, and a plurality of resilient tongues extending from the internal surface of the body portion, each tongue having a free end face spaced from and facing the rib, the disc being trapped, in use, between the rib and the end faces of the tongues, said rib being disposed in a plane lying between the plane of the end faces of the resilient tongues and the plane of the external abutment.
