<p>A b s t r a c t The clamping device of the anti-slip device comprises: a resilient pull or tensioning member (12) extending peripherally of the vehicle wheel; a clamping wire also extending peripherally; two locking members (18, 19); and two release members (22, 23). The pull member (12) has both its ends secured to a rectangular frame (25) which extends around the locking members (18, 19) and the release members (22, 23). The clamping wire (17) is secured relatively to the pull member (12) in a position opposite the frame (25) and has both its free ends (17a, 17b) extending through the locking members (18, 19) and release members (22, 23, in the frame (25). The locking member (18) and associated release member (22) are associated with the wire end (17a) whereas the locking member (19) and release member (23) are associated with wire end (17b). With the anti-slip device fitted and with the release members (22, 23) in the locking position, the locking members (18, 14) allow the clamping device to move relatively to the wire ends (17a, 17b) only in the sense of a shortening of the effective length of the wire (17). With the release members (22, 23) - and therefore the locking members (18, 19) in the release position, the wire ends (17a, 17b) can move relatively to the clamping device in the opposite direction. The anti-slip device can be fitted readily; securing is reliable and take-up is automatic.</p> |
