Abstract
Abstract A hose clamp free from the possibility of a clamp body being accidentally displaced on the peripheral surface of a hose during the insertion of the hose around the terminal part of a connection pipe is attained by the incorporation therein of means capable of coming into resilient contact with the peripheral surface of the hose and inhibiting the clamp body from being displaced on the peripheral surface of the hose when the hose is inserted into the clamping ring part in a radially expanded state.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
103 words
A hose clamp furnished with a tacking function, comprising: a clamp body including an annular clamping ring part for squeezing a hose and a pair of grip parts for filling the role of radially expanding said ring part; a separately formed holder capable of retaining said pair of grip parts in a state of mutual approximation; and displacement inhibiting means capable of coming into resilient contact with the peripheral surface of a hose and inhibiting said clamp body from being displaced on the peripheral surface of said hose when said hose is inserted inside said clamping ring part in a radially expanded state.
Claim 2
Dependent Claim
103 words
A hose clamp furnished with a tacking function, comprising: a clamp body including an annular clamping ring part for squeezing a hose and a pair of grip parts for filling the role of radially expanding said ring part; a separately formed holder capable of retaining said pair of grip parts in a state of mutual approximation; and displacement inhibiting means capable of coming into resilient contact with the peripheral surface of a hose and inhibiting said clamp body from being displaced on the peripheral surface of said hose when said hose is inserted inside said clamping ring part in a radially expanded state.
Claim 3
Dependent Claim
57 words
A hose clamp according to claim 1, wherein said displacement inhibiting means is formed of retaining plates assuming a curved wall different in curvature from said clamping ring part of said clamp body, being slidably attached to the inner side of said clamping ring part and coming into resilient contact with the peripheral surface of said hose.
Claim 4
Dependent Claim
38 words
A hose clamp according to claim 1, wherein said displacement inhibiting means is formed of retaining arms disposed on and tilted from said holder and allowed to come into resilient contact with the peripheral surface of said hose.
