         2 . An enclosure as claimed in  claim 1  further comprising a second projection projecting from a recessed portion of the first face, said second projection also being arranged for engagement with a structure to which the enclosure is to be mounted. 
     
     
         3 . An enclosure as claimed in  claim 2  wherein the first and second projections project from first and second respective parts of the same recessed portion of the first face. 
     
     
         4 . An enclosure as claimed in  claim 2  wherein the first and second projections are arranged for location of at least part of the structure to which the enclosure is to be mounted therebetween. 
     
     
         5 . An enclosure as claimed in  claim 1  wherein said first projection is integral to said first face. 
     
     
         6 . An enclosure as claimed in  claim 2  wherein said second projection is integral to said first face. 
     
     
         7 . An enclosure as claimed in  claim 1  wherein the first projection comprises a free end, distal to the respective recessed portion, wherein said free end does not extend outwards of the outer portion of the first face. 
     
     
         8 . An enclosure as claimed in  claim 2  wherein the second projection comprises an outer surface, distal to the respective recessed portion, and wherein said outer surface does not extend outwards of the outer portion of the first face. 
     
     
         9 . An enclosure as claimed in  claim 1  wherein the first projection comprises a clip. 
     
     
         10 . An enclosure as claimed in  claim 2  wherein the second projection comprises a hook. 
     
     
         11 . An enclosure as claimed in  claim 1  further comprising at least one vent provided on a face thereof. 
     
     
         12 . An enclosure as claimed in  claim 1  wherein the enclosure houses at least one cooling component. 
     
     
         13 . An enclosure as claimed in  claim 12  wherein said cooling component comprises a heatsink. 
     
     
         14 . An enclosure as claimed in  claim 1  wherein the enclosure houses an electronic circuit and an apparatus for protecting said electronic circuit from an airflow, said apparatus comprising a cover means for covering at least part of the electronic circuit and a guide means for guiding an airflow around the electronic circuit. 
     
     
         15 . An enclosure as claimed in  claim 1  wherein the structure to which the enclosure is to be mounted comprises a DIN rail. 
     
     
         16 . An enclosure as claimed in  claim 1  wherein said first face comprises a rear face of the enclosure. 
     
     
         17 . An enclosure as claimed in  claim 1  wherein said enclosure is arranged to house heat generating components.
