Patent ID: 7124453

Claim:
A connecting device for connecting a shower head assembly to a wall-mount water supplying pipe, comprising: a tubular coupler including an inner tubular wall and an outer tubular wall which surround an axis and which are opposite to each other in radial directions, and having first and second tubular end walls which extend respectively and radially from said outer tubular wall to said inner tubular wall and which are opposite to each other in an axial direction parallel to the axis, said inner tubular wall defining a water duct therein which is adapted to be disposed downstream of the water supplying pipe to permit water flow from said second tubular end wall to said first tubular end wall; a hollow adapter having a surrounding wall which is disposed to surround and which is turnable relative to said outer tubular wall about the axis, and which includes outer and inner wall surfaces opposite to each other in radial directions, and an inner barrier wall which extends radially and inwardly from said inner wall surface and which confronts said first tubular end wall, said inner wall surface cooperating with said inner barrier wall to define a water passage which is disposed downstream of said water duct when said surrounding wall surrounds said outer tubular wall, said adapter having an outlet port which is disposed downstream of said water passage, and which extends in a radial direction relative to the axis so as to be adapted to couple with the shower head assembly; and a retaining member which is disposed to be distal from said inner barrier wall, and which extends inwardly and radially from said inner wall surface and angularly along said inner wall surface about the axis such that when said inner wall surface is turned relative to said outer tubular wall, said retaining member is kept in slidable contact with said second tubular end wall so as to prevent movement of said adapter away from said coupler along the axis.
