Abstract
Abstract In a snap buckle, the plug member 1 has a pair of resilient locking strips, each having on its outer surface an engaging portion, and a pair of guide strips outside the locking strips, each having an inner edge portion substantially in alignment with the respective engaging portion. The companion socket member has a pair of locking walls and a pair of inwardly bent resilient push levers outside the locking walls. When inserting the plug member into the socket member, the engaging portions engages the locking walls to bring the inner edge portions of the guide strips into contact with the side surfaces of the locking walls, causing the pushing portions of the push levers to resiliently contact the heads of the locking strips. Pressing the pushing levers inwardly releases the connection of the plug and socket members. The guide strips prevents either any accidental release or any misinsertion.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
177 words
A snap buckle comprising a flat tube shaped socket member and a plate shaped plug member releasably insertable into said socket member, wherein said plug member has a base, a pair of resilient locking strips projecting in a common direction from said base, each locking strip having on its outer surface an engaging portion, and a pair of guide strips projecting in said common direction from said base so as to be located outwardly of said locking strips and having a length smaller than said locking strips, each guide strip having an inner edge portion substantially in alignment with the respective engaging portion, and wherein said socket member has a pair of locking walls engageable with the respective engaging portions of said locking strips when said plug member is inserted into said socket member, and a pair of inwardly bent resilient push levers extending from opposite outermost surfaces of a socket mouth edge and terminating in a pair of pushing portions resiliently contactable with said locking strips when said plug member is inserted into said socket member.
Claim 2
Dependent Claim
