  • Patent number: 9103477
    Abstract: In a strap-band type connecting device (1), provided is a housing (4) work-hardened and has a bottomed frame (4c) having a frame portion (4b) and a bottom base (4a) in one piece. The housing (4) has a strength and rigidity higher enough to resist a torsional force (K) when a rod screw (9) is rotationally operated. Even when the rod screw (9) is rotationally operated accidentally with a magnitude more than an allowable amount of torque, it is possible for the housing (4) to resist the torsional force (K) with a sufficient strength insured, so as to keep the strap band (3) winding around the connection hose (2) in a favorable condition for an extended period of time.

  • Patent number: 8806721
    Abstract: In a strap-band type connecting device (1), a strap band (3) has an array of teeth (8), each of which forms a bridged brace (10) between the neighboring slits (8a) to make a helical thread (9a) engage with the bridged brace (10) when a rod screw (9) is brought at the helical thread (9a) into engagement with the slits (8a) within a housing (4). The bridged brace (10) is curvedly deformed to provide a width-reduced groove (10a) in its lengthwise direction (P) so as to form a cross piece segment (11, 13), a geometrical moment of inertia of which increases along a circumferential direction (R) of the strap band (3) with a sufficient rigidity provided to resist against a bending force from the helical thread (9a) upon rotationally operating the rod screw (9).
