1,264,097. Band clamps. LEGRAND S.A. 3 March, 1970 [7 March, 1969; 15 Jan., 1970], No. 10207/70. Heading E2B. A releasable plastics band clamp comprises a ratchet-toothed flexible strap 11 which may be secured in the eye 12 of a securing head by a ratchet-toothed detent 14 connected to the eye. The band is held in contact with the detent teeth by guides 20A, 20B. The abutment 18 may also have retaining teeth. The clamp is released, without damage, by forcing off the detent 14. A block 65, Fig. 8, may serve for fixing to a wall. The detent may be at right angles to the strap, Fig. 10. The detent may be hinged in various ways to the eye, and held by dowels or wedging action (Figs. 13- 18, not shown). The holding teeth 78 on the fastener 76 may, instead be on the inner wall of the eye 70. In this case the strap is toothed on its other side. |
