Abstract

A hand shower has a shower housing having an inner end formed centered on an axis with an axially open central recess and an outer end carrying a shower head. A male coupling part adapted to be fixed to the end of a supply hose has a tubular outlet end engageable axially in the housing inner end. A latch element can be displaced radially of the axis in the inner end between a holding position engaging and axially retaining the coupling part in the recess and a freeing position allowing the coupling part to move axially freely into and out of the recess. The housing has a central feed tube forming the inner and outer ends and at least one rigid outer housing part surrounding and completely enclosing the central feed tube. Furthermore the shower includes a pair of such latch elements radially oppositely displaceable between the positions. These elements can be fitted without soldering or fusing into the housing for a very inexpensive and simple assembly of the device.
