<p>A fastening device 1 for securing an instrument panel 3 to a vehicle body 5 comprising a first striker member 7 for passing through a bore 9 in the instrument panel 3, the first striker member 7 comprising an enlarged head 11, and a nose 13, extending from the head 11 in a first direction A and coupled to the head 11 by a shank 15 having a transverse cross section taken along a first plane B substantially perpendicular to the first direction A which is smaller than the transverse cross section of the head 11, the nose 13 having a transverse cross section 17 for at least part of its depth greater than the transverse cross section of the shank 15 such that a shoulder area 19 is defined, the nose 13 tapering from a region 17 of large transverse cross sectional area away from the shank to the nose tip 21 , the longitudinal cross section C of the nose being substantially constant in a lateral direction orthogonal to the first direction (longitudinal cross section taken in a plane parallel to the plane of the paper in figure 1), and a second catch member 23 for mounting on the vehicle body 5, including mounting means 25 and a nose receiving housing 27 shaped to receive the nose 13 and having a longitudinal cross section which is substantially constant in a lateral direction, the nose receiving housing 25 having a mouth 29 into which the nose 13 may be pushed, a cavity 31 of depth greater than the depth of the nose 13 taken from the nose tip 21 to the shank 15 and whose transverse cross section is at least for some of its depth greater than the greatest transverse cross section 17 of the nose, and a throat region 33 of smaller transverse cross section, at least the throat region 33 of the nose receiving housing having resilient walls to grip the nose 13 when inserted in the housing 25, the throat 33 and cavity 31 defining a shoulder region 35 which inhibits the removal of the nose 13 from the cavity 31 by the shoulder 19 of the nose 13 bearing against the shoulder 35 of the cavity 33.</p> |
