[Also in Division G1] An instrument assembly comprises an instrument 23 (speedometer or revolution counter) carried by the rear wall 32 of a box behind a vehicle fascia panel, a driving cable whose inner core is drivably connected to an input spindle of the instrument 23 and a connector 28 connecting the outer sheath 26 of the cable to the wall 32 without restraining the withdrawal of the instrument 23. The connection is made releasably between a part formed integrally with the wall 32 round an aperture 33 and a part secured to the sheath 26 with or without a supplementary fastening part. A part 28 secured to the sheath 26 has flexible limbs 31 which deform inwardly when pushed through a lip 35 (directed inwardly from a ring 144 joined to the wall 32 by a skeletal structure 143, Fig. 2, or from a wall (34) round the aperture (33), Fig. 1 (not shown)). When the limbs 31 pass the lip 35 a flange 30 engages its rear side and the limbs 31 spring out to engage its front side. To turn the drive through a right angle, a suitable transmission unit, Fig. 3 (not shown), may be used, the sheath being connected to the unit and the unit to the wall 32 by two connectors similar to that described. When the wall 32 is formed of resilient plastics, a simpler form can be used, Fig. 4 (not shown), in which a lip springs into a groove. Further elaborations of these connectors are described provided with forward and rear projections to facilitate detachment of the cable from the wall from the front (after removing the instrument) or from the rear (without). A complex connector in which a ferrule (120) is retained in a socket (116) by a detent 125, Fig. 9, has limbs 130 that snap into a groove in the ferrule when fully inserted and can be withdrawn by rotation through manipulating forward projections 127 or projection 129 at the rear so that stepped portions of slots engage the centres of limbs 130 and force them to ride out of the groove.
