A connector, comprising:

• a housing having a front end for connection with a mating housing and a rear end opposite the front end,
• a resiliently displaceable lock arm for holding the housing connected with a mating housing, the lock arm including an arm main body extending substantially from the front end to the rear end of the housing, a front support joining the arm main body to a portion of the housing substantially adjacent the front end and first and second rear supports extending transversally from the arm main body and joining the arm main body to the housing at a position forward of the rear end, a lock portion forward of the rear support and being engageable with an interlocking portion of the mating housing and an unlocking portion provided substantially at the rear end of the housing to resiliently displace the arm main body in an unlocking direction,
• first and second protection walls projecting from the housing at opposite respective sides of the lock arm and in proximity to the rear end of the housing, and
• first and second touch restricting portions cantilevered respectively from the first and second protection walls at locations spaced above the housing and in positions rearward of the first and second rear supports, the first and second touch restricting portions projecting towards opposite projecting ends of the unlocking portion for restricting touch from substantially above and outside.
