Is it possible to change the socket of the ATMEL chip in ARDUINO UNO into a ZIP socket ?

I suppose if you're a decent at soldering you can.
Go one pin at a time, heat the pin & pull it out of the socket with pliers.
Are you damaging your 328 in some way that it needs frequent replacing?

Or are you looking for an easy way to bootload/program bare chips?

Install a socket on a board like this

Get an AVR ISP programmer for installing bootloaders

and get an FTDI Basic as the a USB/Serial adapter for programming sketches.

Basically no. While a 28pin slim DIP socket has the same pin spacing as the standard dip socket used on the arduino board, the Zip socket is physicall longer and wider and will interfer with other components already mounted on the board. You would have to build some kind of 'stand-off' arrangement to allow the zip socket to be mounted above the board surface. The following isn't a good picture of what I did to allow a zip socket to attach to a arduino standalone board, but it might give you a good idea of how much larger a zip socket is then a standard dip socket and why you need to be creative.

My intention is just to duplicate the programmed arduino uno 238 chip , so I can insert it in another custom
board that will implement the arduino uno + the external components used at design time.

i think that ARDUINO UNO rev 4 should do just that .
I wonder why it was not done in rev 3 ...

No need really - use the optiloader with the barechip in a solderless breadboard, no expensive ZIP socket needed.

// If the aim is to reprogram the bootloader in one Arduino using another
// Arudino as the programmer, you can just use jumpers between the connectors
// on the Arduino board.  In this case, connect:
// Pin 13 to Pin 13
// Pin 12 to Pin 12
// Pin 11 to Pin 11
// Pin 10 (of "programmer") to RESET (of "target" (on the "power" connector))
// +5V to +5V and GND to GND.  Only the "programmer" board should be powered
//     by USB or external power.

westfw even posted a video of it in action somewhere.

The link leads to a zip file called optiLoader4_4.zip containing optiloader.h and optiloader.pde.
No video  =(

Just in case you're trying to find one, it isn't a zip socket, it's a ZIF (zero insertion force) socket.
