1. A razor unit comprising:

  • A handle including an attachment in the form of at least one prong extending outwardly therefrom; and

    a disposable cartridge containing at least one blade and having a separate enclosing chamber positioned thereon and extending therefrom;

    said prong being insertable into said chamber and enclosed within the chamber with an underside of said prong being in contacting relationship with an underside of the chamber to form a fit which supports the cartridge on the handle;

    said underside of said chamber and said underside of said prong together forming a resiliently supported tooth and a clearance slot, located at the innermost point of said chamber, said resiliently supported tooth being positioned to snap into and to be held securely in said clearance slot when said prong is fully inserted into said chamber, said tooth and said slot forming an interference fit which is sufficient to hold the cartridge onto the handle during shaving but which allows a force applied to said cartridge in a direction along said prong and outward from said handle to disengage the tooth from the clearance slot to permit removal of the cartridge from the handle.
