Patent number: 9103477Abstract: 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.Type: GrantFiled: March 15, 2013Date of Patent: August 11, 2015Assignee: Sogyo Co., Ltd.Inventors: Ryuichi Takagi, Shigenobu Kimura
