Holder for a radiotelephone

The holder (200) has a holding arrangement and a contacting unit held in an open position by at least one retaining arrangement (25), which releases the holding arrangement and/or the contacting unit if the telephone (201) operates a switch in a shell of the holder with a rear part of the telephone. The holding arrangement can be deployed linearly from the open position into an operating position against the contacting unit or a counter piece.
